Plus, it comes together in just one baking dish with minimal prep, making it a go-to favorite for families craving something simple yet satisfying.

What Kind of Potatoes Should I Use?

Frozen diced potatoes (sometimes called southern-style hash browns) are perfect for this dish. They save you the peeling and chopping time while delivering the soft, tender texture you want in a casserole. Avoid shredded hash browns, which can turn mushy, and instead go for the small cubed variety for that perfect bite.

Ingredients for the Cheesy Beef & Frozen Potato Casserole

Frozen diced potatoes: The base of the casserole, providing a hearty, starchy bite that holds up well when baked.
Ground beef: Adds savory richness and protein. Browned and seasoned, it brings comfort-food flavor.
Bell peppers: A touch of sweetness and a bit of color, bell peppers help balance the dish.
Onion: Essential for building flavor. Sautéing it with the beef adds depth to the casserole.
Cream of mushroom soup: Acts as the creamy binder, holding everything together.
Sour cream: Brings tangy richness and creaminess to the base.
Cheddar cheese: Melty, sharp, and comforting—a must-have for that cheesy pull.
Salt, pepper & seasoning blend: Boosts the overall flavor and adds a kick of personality to the mix.

How To Make the Cheesy Beef & Frozen Potato Casserole

Step 1: Brown the Beef

In a large skillet over medium heat, cook ground beef until browned and no longer pink. Drain excess fat.

Step 2: Add Veggies

Add diced onions and bell peppers to the skillet with the beef. Cook until softened, about 5 minutes.

Step 3: Mix the Creamy Base

In a large mixing bowl, combine cream of mushroom soup, sour cream, half the shredded cheddar cheese, salt, pepper, and your seasoning blend.

Step 4: Bring It All Together

Add the frozen diced potatoes and beef-veggie mixture to the creamy base. Mix everything until well coated.

Step 5: Bake It

Transfer the mixture into a greased 9×13-inch casserole dish. Top with the remaining cheddar cheese. Bake uncovered at 350°F for 40-45 minutes, or until bubbly and golden on top.

Tips for Serving and Storing This Casserole

This casserole is best served hot straight from the oven, with the cheese still gooey and melty. If you have leftovers, store them in an airtight container in the fridge for up to 4 days. Reheat in the oven or microwave until warmed through. This dish also freezes well before or after baking—just be sure to wrap tightly.
