This is one of those keto recipes for ground beef that truly proves you don’t need a ton of fancy ingredients to make something amazing.
Essential Ingredients for Your Keto Casserole With Ground Beef
- 1 lb ground beef – I like to use an 80/20 blend because it gives you great flavor and keeps things nice and moist.
- 1 cup yellow onion, finely chopped – You want these pieces small so they cook down nicely without being chunky.
- 2 cloves garlic, minced – Fresh is best here, but you can use garlic powder in a pinch!
- 1 teaspoon salt – To bring out all those yummy flavors.
- 1/2 teaspoon black pepper – Just a little kick!
- 1/2 teaspoon paprika – Adds a lovely color and subtle smoky note.
- 1/4 teaspoon cayenne pepper (adjust to taste) – This is your heat control! Start with this and add more if you like it spicy.
- 1 cup heavy cream – This is what makes our sauce rich and creamy.
- 1 cup shredded cheddar cheese – The star of the cheesy show!
- 1/2 cup shredded mozzarella cheese – Because more cheese is always a good idea, right? It gets nice and melty.
Ingredient Notes and Smart Substitutions
So, about those ingredients! Like I mentioned, the 80/20 ground beef is my go-to because it has just the right amount of fat to make this casserole super flavorful and moist. If you’re really watching fat, you could go leaner, but I’d maybe add a tiny bit more oil when cooking the onions. For the onion, a yellow or white onion works perfectly, just make sure it’s chopped up nice and small. And for the cheese, feel free to mix it up! A good sharp cheddar is fantastic, but a Monterey Jack or even a Colby blend would be delicious too. The cayenne is totally adjustable – if you’re not a fan of heat, just leave it out or use a tiny pinch. It’s all about making this keto casserole with ground beef perfect for *you*!

Finishing and Baking Your Cheesy Keto Ground Beef Casserole

Pop it into that preheated oven and bake for about 15-20 minutes. You’re looking for it to be bubbly and have that gorgeous golden-brown cheese on top.

It makes a surprising difference in the final texture, giving you a consistent bite instead of some mushy bits and some dry ones. And for the sauce, don’t over-simmer it! It’s supposed to thicken a bit on the stovetop, but it’ll get even thicker and richer as it bakes in the oven. Trust me, these little things make a huge difference in turning a good keto casserole with ground beef into an *amazing* one!
