This round beef and potato casserole shaves down your typical cooking time without compromising flavor or texture. With precise layering and pre-slicing, you’ll be able to streamline your steps efficiently.
Step-by-Step Instructions
Step 1: Prep and Preheat
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13 baking dish with olive oil or nonstick spray.
Pro Tip: Use a mandoline to evenly slice the potatoes. This ensures quicker and more uniform baking.
Step 2: Cook the Ground Beef
In a large skillet over medium-high heat, brown the ground round beef along with the diced onions and garlic for 6–8 minutes. Season with salt, pepper, thyme, and smoked paprika.
Tip: Drain any excess liquid to prevent a soggy casserole base. That’s why ground round is ideal—less fat, less mess.
Step 3: Create the Creamy Base
In a bowl, whisk the cream of mushroom soup and milk until smooth. This will be your binding sauce that adds creamy richness to the dish.
Variation: For an herby kick, mix in a tablespoon of pesto or Italian seasoning to the soup base before assembling.
Step 4: Layer the Casserole
In your prepared dish, place a single layer of sliced potatoes, followed by a layer of the cooked beef mixture. Pour some of the soup mixture over the top, followed by a sprinkle of cheese. Repeat until all ingredients are used, finishing with cheese on top.
Layer Order:
- Potatoes (⅓)
- Beef (⅓)
- Soup mix
- Cheese
- Repeat ×2

Step 5: Bake and Finish
Cover loosely with foil and bake for 40 minutes. Remove foil, then bake uncovered for an additional 15 minutes to brown and bubble.
Rest for 5 minutes before serving to allow the layers to set.

Common Mistakes to Avoid
✅ Leaving potatoes too thick: Thick slices won’t cook through. Aim for ⅛-inch thickness.
✅ Not draining the beef: Excess fat leads to a greasy base. Use paper towels to blot if necessary.
✅ Adding all cheese at the start: Instead, layer lightly and save most for the top—this prevents sogginess.
✅ Skipping the rest time: Let it sit post-bake for optimal sliceability.
✅ Overbaking: Too long in the oven, and your potatoes dry out. Stick with the timer and check after 40 minutes.

FAQs
❓Can I use a slow cooker instead?
Yes! Brown the beef, layer in your slow cooker, and cook on low for 6–7 hours or high for 3–4. The potatoes will become melt-in-your-mouth tender.
❓Can I prep this recipe overnight?
Absolutely. Assemble everything, cover, and refrigerate overnight. Just let it sit at room temperature for 15–20 minutes before baking to ensure even cooking.
❓Is there a vegetarian alternative?
Yes, swap beef for sautéed mushrooms or meatless crumbles and use vegetable-based cream soup. Add extra veggies like broccoli or spinach for body and flavor.
❓What’s the best potato to use?
Yukon Gold or russet potatoes are best because they hold shape while offering tenderness. Avoid waxy potatoes like reds.
❓How do I make it gluten-free?
Use a certified gluten-free cream of mushroom soup and double-check seasonings and cheese. Many brands now offer gluten-free options for casseroles.
