Step-by-Step Instructions

Step 1: Brown the Beef

Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it into small pieces with a spoon.

Add the diced onion and cook for another 3–4 minutes until softened. Stir in the minced garlic and cook for 30 seconds.

Drain any excess grease.

Step 2: Prepare the Sauce

In a medium bowl, combine:

Cream of mushroom soup
Cream of cheddar (or chicken) soup
Beef broth
Worcestershire sauce
Italian seasoning
Paprika
Salt
Black pepper

Whisk until smooth.

If using sour cream, stir it into the mixture now.

Step 3: Layer the Ingredients

Lightly grease the inside of your slow cooker.

Layer in this order:

Half of the sliced potatoes
Half of the ground beef mixture
Half of the mixed vegetables
One-third of the cheese
Half of the sauce

Repeat the layers with the remaining potatoes, beef, vegetables, sauce, and another third of the cheese.

Reserve the remaining cheese for later.

Step 4: Slow Cook

Cover with the lid.

Cook on:

Low: 4–6 hours
High: 2–3 hours

The casserole is ready when the potatoes are fork-tender.

Step 5: Add the Cheese

About 15 minutes before serving, sprinkle the remaining cheddar cheese over the top.

Cover again and allow the cheese to melt completely.

Tips for the Best Slow Cooker Ground Beef Casserole

Brown the beef before adding it to the slow cooker for the best flavor and texture.
Slice potatoes evenly so they cook at the same rate.
Avoid lifting the slow cooker lid during cooking, as this releases heat and extends cooking time.

If the casserole seems too thick, stir in a little extra beef broth near the end of cooking.

Frequently Asked Questions

Can I use ground turkey instead of ground beef?

Yes. Ground turkey or ground chicken makes a lighter version while still providing plenty of flavor.

Do I have to brown the beef first?

It’s highly recommended. Browning develops richer flavor and removes excess fat, resulting in a better texture.

Can I make this casserole ahead of time?

Yes. Assemble the casserole the night before, refrigerate the slow cooker insert if your model allows, and begin cooking the next day.

What potatoes work best?

Yukon Gold and Russet potatoes are both excellent choices because they become tender and absorb the savory flavors well.

Can I make this gluten-free?

Yes. Use certified gluten-free condensed soups, Worcestershire sauce, and broth, and verify that all other ingredients are gluten-free.
