Ingredients:

  • 1 tablespoon olive oil or vegetable oil
  • 1 teaspoon salt, divided
  • 1/2 teaspoon black pepper, divided
  • 1 teaspoon paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
• For the Potatoes and Aromatics:
  • 4-5 medium-sized Yukon Gold potatoes (about 2.5 pounds), peeled and thinly sliced (about 1/8-inch thick)
  • 1 large yellow onion, finely diced
  • 4 cloves garlic, minced
• For the Cheesy Sauce:
  • 4 cups beef broth (low sodium preferred)
  • 1 cup heavy cream or half-and-half
  • 2 tablespoons all-purpose flour or cornstarch (for thickening, optional)
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon dried thyme
  • 1/2 teaspoon dried rosemary, crushed
  • Pinch of red pepper flakes (optional, for a slight kick)
  • Salt and black pepper to taste
• For the Cheese and Garnish:
  • 3 cups shredded sharp cheddar cheese, divided
  • 1/2 cup grated Parmesan cheese (optional, for extra depth)
  • Fresh parsley or chives, chopped, for garnish (optional)

Preparing the Steak and Aromatics

1. Prepare the Steak: First things first, let’s get our steak ready for this wonderfully Slow Cooker Steak And Cheddar Potato Casserole Hearty Cheesy And Comforting. Take your chosen cut of beef – sirloin, chuck, or round steak all work beautifully here – and trim away any excessive fat or gristle. You want nice, lean pieces for the casserole. Now, cut the beef into uniform 1-inch cubes. Uniformity is key here because it ensures that all the steak cooks evenly in the slow cooker, resulting in tender, melt-in-your-mouth bites rather than some chewy and some perfect. In a medium bowl, toss the cubed steak with 1/2 teaspoon of salt, 1/4 teaspoon of black pepper, the paprika, garlic powder, and onion powder. Make sure every piece is nicely coated with the seasoning; this is where a lot of the flavor infusion begins.
2. Sear the Steak: This step is absolutely crucial for building deep, robust flavor in our casserole. Trust me, do not skip searing! Heat the olive oil or vegetable oil in a large skillet or Dutch oven over medium-high heat until it shimmers. Once the pan is hot, add the seasoned steak cubes in a single layer, making sure not to overcrowd the pan. If you add too much at once, the temperature of the pan will drop, and the steak will steam instead of sear, preventing that gorgeous brown crust we’re looking for. You might need to do this in two or three batches. Sear the steak for 2-3 minutes per side, just until a beautiful golden-brown crust forms. We’re not cooking it through at this stage; we’re simply locking in flavor and creating delicious fond (the browned bits) at the bottom of the pan. Remove the seared steak to a plate and set aside.
3. Sauté the Aromatics: Reduce the heat in the same skillet to medium. If there’s not enough oil left, add another teaspoon. Add the finely diced yellow onion to the skillet. Sauté the onion, stirring occasionally, for about 5-7 minutes, or until it softens and becomes translucent. As the onion cooks, it will also help scrape up some of those delicious browned bits from the steak, which will add even more depth to our sauce. Once the onions are soft, add the minced garlic. Cook for another 1 minute, stirring constantly, until the garlic is fragrant. Be careful not to burn the garlic, as burnt garlic can turn bitter and ruin the flavor profile.
4. Deglaze and Build the Sauce Base: Now for the magic! Pour about 1 cup of the beef broth into the skillet with the onions and garlic. Use a wooden spoon or spatula to scrape up all the flavorful browned bits (fond) from the bottom of the pan. This step, called deglazing, is fantastic for intensifying the savory notes in our casserole. Allow the broth to simmer for a minute, reducing slightly.

Assembling the Slow Cooker Steak And Cheddar Potato Casserole

5. Prepare the Potatoes: While your aromatics are cooking, focus on the potatoes. Peel your Yukon Gold potatoes (or Russets, if you prefer, but Yukon Golds tend to hold their shape better and offer a creamier texture) and slice them thinly, about 1/8-inch thick. A mandoline slicer is incredibly helpful here to ensure consistent thickness, which is vital for even cooking. If you don’t have one, a sharp chef’s knife and a steady hand will do the trick. Try to keep them as uniform as possible.
6. Whisk the Sauce: In a large bowl, combine the remaining 3 cups of beef broth, the heavy cream, Worcestershire sauce, dried thyme, and crushed dried rosemary. If you like a little warmth, now is also a good time to stir in a pinch of red pepper flakes. Whisk everything together thoroughly until well combined. This is our luscious, creamy sauce that will cook down and coat every element of our hearty and comforting Slow Cooker Steak And Cheddar Potato Casserole. Taste the sauce and adjust seasonings with salt and black pepper as needed. Remember, the beef and cheese will add saltiness later, so start conservative.
7. Optional Thickening Slurry: If you prefer a thicker sauce, you can prepare a cornstarch or flour slurry now. In a small bowl, whisk together 2 tablespoons of all-purpose flour or cornstarch with 1/4 cup of the cold beef broth (taken from the 3 cups you set aside). Once completely smooth with no lumps, whisk this slurry into your main sauce mixture. This will help prevent lumps in your final casserole and ensure a beautifully thick, clingy sauce.
8. Layering in the Slow Cooker: This is where our Slow Cooker Steak And Cheddar Potato Casserole truly comes together. Lightly grease the inside of a 6-quart or larger slow cooker with cooking spray or a little oil. We’re going to build this casserole in layers to ensure all flavors meld beautifully and the potatoes cook evenly.
   • First Layer: Spread about one-third of the thinly sliced potatoes evenly across the bottom of the slow cooker.
   • Second Layer: Follow with half of the seared steak cubes, distributing them over the potatoes.
   • Third Layer: Sprinkle about 1 cup of the shredded sharp cheddar cheese over the steak. If using Parmesan, sprinkle half of it here too.
   • Fourth Layer: Spoon about one-third of the onion and garlic mixture over the cheese.
   • Fifth Layer: Pour about one-third of the creamy beef broth mixture evenly over everything.
   • Repeat: Now, repeat the layers: another third of the potatoes, the remaining half of the steak, another cup of cheddar cheese (and remaining Parmesan if using), the rest of the onion and garlic mixture, and another third of the liquid sauce.
   • Top Layer: Finish with the remaining one-third of the sliced potatoes. Pour the very last of the creamy beef broth mixture over the top layer of potatoes, ensuring it spreads as evenly as possible. You want to make sure the top layer of potatoes is submerged in the liquid to prevent them from drying out and to ensure they cook properly.
     

     Pro Tip for Even Cooking:

     Gently press down on the layers with the back of a spoon to help compress them slightly and ensure all ingredients are in contact with the liquid. This encourages uniform cooking and maximizes flavor absorption throughout this cheesy and comforting dish.

Slow Cooking and Finishing Touches

9. Slow Cook to Perfection: Secure the lid on your slow cooker. Cook on LOW for 6-8 hours or on HIGH for 3-4 hours. The cooking time can vary based on your specific slow cooker and how thick your potato slices are. You’ll know it’s ready when the steak is incredibly tender and easily pulls apart with a fork, and the potatoes are fork-tender and creamy, not mushy. The sauce should be thickened and bubbling at the edges.

   Checking for Doneness:

   Around the 6-hour mark on LOW (or 3 hours on HIGH), insert a fork into a potato slice in the middle of the casserole. If it slides in easily with no resistance, the potatoes are done. Check a piece of steak as well to ensure it’s tender. If not, continue cooking for another 30-60 minutes.

10. Add Final Cheese Layer: About 30 minutes before serving, or once the casserole is fully cooked, remove the lid. Sprinkle the remaining 1 cup of shredded sharp cheddar cheese evenly over the top of the casserole. This final layer of cheese will melt into a glorious, gooey, golden crust. Replace the lid and continue cooking for another 15-30 minutes, or until the cheese is beautifully melted and bubbly. If your slow cooker has a “warm” setting, you can switch it to that to melt the cheese if you’re worried about overcooking.
11. Rest and Serve: Once the cheese is melted, turn off the slow cooker. For the best texture and to allow the sauce to set slightly, let the Slow Cooker Steak And Cheddar Potato Casserole Hearty Cheesy And Comforting rest for about 10-15 minutes with the lid off. This brief resting period helps the flavors to further meld and makes it easier to scoop without it being too runny. Garnish with fresh chopped parsley or chives, if desired, for a touch of freshness and color. Serve hot and enjoy this incredibly satisfying, rich, and flavorful casserole! It’s truly a complete meal in one pot and perfect for a chilly evening or a gathering with loved ones.

Conclusion:

Friends, if there’s one recipe I truly urge you to add to your culinary repertoire, it’s this one. The sheer simplicity of preparation, combined with an explosion of rich, satisfying flavors, makes it an absolute winner in every sense. Imagine the incredible sensation of walking through your front door after a long, demanding day, only to be greeted by the savory, comforting aroma of tender, perfectly cooked steak, creamy potatoes, and wonderfully melted cheddar cheese, all bubbling away gently in your slow cooker. It’s more than just a meal; it’s a heartwarming promise of comfort and deep satisfaction, waiting patiently to be enjoyed with minimal effort on your part. The inherent beauty and convenience of the slow cooker truly shines in this recipe, effortlessly transforming humble, everyday ingredients into something truly extraordinary and utterly memorable. You genuinely deserve a delicious, stress-free dinner that nourishes both body and soul, and I can assure you, this recipe delivers precisely that, every single time.

While this casserole is undeniably a complete and robust meal on its own, perfectly capable of standing alone, I personally love serving it with a few thoughtfully chosen accompaniments to elevate and round out the entire dining experience. A vibrant, crisp green salad, perhaps dressed with a light, tangy vinaigrette, offers a wonderfully refreshing contrast to the inherent richness and creamy textures of the dish, cleansing the palate beautifully between bites. For those of us who simply adore mopping up every last, flavorful drop of that incredible, cheesy sauce – and believe me, there will be plenty to savor – a warm, crusty loaf of artisanal bread or a soft, pillowy dinner roll is an absolute, non-negotiable must-have. And for that extra touch of visual appeal, a burst of freshness, and a delicate, mild oniony bite, a generous sprinkle of freshly chopped chives or thinly sliced green onions over each individual serving just before you dig in, works wonders to elevate both the presentation and the overall flavor profile. Additionally, a dollop of cool, tangy sour cream or even a spoonful of plain Greek yogurt on top is a fantastic addition, introducing a delightful cool and creamy counterpoint that you’ll undoubtedly adore.

One of the many things I deeply adore about this particular recipe is its incredible versatility and adaptability. Please, don’t be afraid to make it truly your own and experiment with various modifications! For all the fellow cheese enthusiasts out there, consider experimenting by swapping out some of the traditional sharp cheddar for creamy Monterey Jack, a smoky gouda, or even a robust, sharp provolone to introduce exciting new flavor dimensions and textures. If you’re looking to boost the vegetable content and make it even more wholesome, thinly sliced mushrooms, finely diced bell peppers (red, yellow, or green!), or even a handful of frozen peas added in during the last hour of cooking would all be absolutely wonderful and welcomed additions. For a touch of sophisticated, herbaceous complexity, a sprig of fresh rosemary or a few sprigs of fragrant thyme tucked into the slow cooker will infuse the entire dish with a beautifully aromatic quality that lingers delightfully. And for those who appreciate a bit of warmth and a gentle kick, a pinch of red pepper flakes or a quick dash of your favorite hot sauce stirred in can add a welcome, subtle heat without overpowering the other flavors. You could even experiment with different cuts of steak, although I personally find that a good quality chuck roast or sirloin works absolutely beautifully, yielding incredibly tender results.
