Lean Ground Beef – The leaner the better. I like to use 90/10. (see Recipe Tips) Other ground meat that you can use: ground chicken or ground turkey.

Onion – White onions are slightly milder. If you like a little stronger onion flavor, use a yellow onion or red onion.

Bell Peppers – I love the flavor of yellow, orange, and red peppers. They are sweeter and milder than green peppers. Use your favorite or what you have on hand.

Diced Tomatoes – If you love Mexican flavors, use canned diced tomatoes with green chiles in this taco salad recipe.

Homemade Taco Seasoning – Chili powder, ground cumin, garlic powder, oregano, black pepper, red pepper flakes, and sea salt.

Cream Cheese – This helps thicken the keto taco bake just a bit. (not pictured)

Shredded Cheese – Use your favorite cheese. The most popular cheeses for this Mexican casserole are cheddar cheese, monterey jack, and shredded Mexican cheese blend.

Recipe Tips

When lean ground beef 90/10 is browned, there is enough fat to cook the onion and bell pepper. 

If you use ground beef that is not lean there is often a lot of excess fat that you may need to drain off or the baked casserole can be too runny. 

A great option is to brown the ground meat separately, draining excess liquid. 

Saute’ chopped onion and bell pepper in a little olive oil or avocado oil. Mix with ground meat.
