Ingredients That Keep It Simple and Delicious
One of the best things about this dish is how simple the ingredients are. You likely have most of them on hand already, which means less time shopping and more time enjoying.
Here’s what you’ll need for the base:
- Ground beef – rich in flavor and fat, perfect for keto
- Taco seasoning – homemade or store-bought (just watch for added sugar)
- Chopped onions and garlic – for depth of flavor
- Diced tomatoes or salsa – adds moisture and tang
- Shredded cheddar cheese – for that melty, gooey finish

And for the fresh topping:
- Shredded lettuce
- Diced avocado
- Chopped tomatoes
- Sour cream
- Jalapeños (optional for heat)
These ingredients come together to create a dish that is not only low in carbs but also packed with flavor and texture.
Step-by-Step: How to Make It in Just 20 Minutes
This casserole comes together quickly, making it perfect for weeknights. Here’s how to get it done:
Step 1: Cook the Beef
In a large skillet, cook the ground beef over medium heat until browned. Drain the excess grease, then stir in your taco seasoning, a bit of water, and chopped onions. Let it simmer for a few minutes to let the flavors meld.
Step 2: Assemble the Casserole
In a casserole dish, spread the beef mixture evenly. Top it with a layer of diced tomatoes or salsa, followed by a generous amount of shredded cheese.
Step 3: Bake or Broil
You don’t need to bake this long—just enough to melt the cheese. A quick 5-minute broil will do the trick, giving you that irresistible bubbly cheese topping.

Step 4: Add the Fresh Toppings
Once out of the oven, let the casserole cool slightly. Then top it with shredded lettuce, diced tomatoes, avocado, and sour cream. If you like spice, sliced jalapeños or a drizzle of hot sauce is a great touch.
Tips for the Best Keto Taco Salad Casserole
- Use full-fat cheese and sour cream to stay keto and add creaminess.
- Add a squeeze of lime over the fresh toppings for a bright finish.
- Make your own keto taco seasoning with chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper.
- Want extra crunch? Sprinkle crushed pork rinds on top before serving.
This recipe is also easy to modify—add mushrooms, zucchini, or bell peppers to the meat mixture for extra veggies, or swap ground beef for ground turkey or chicken if you prefer.
A Perfect Dish for Meal Prep
This casserole is not only a great dinner but also ideal for meal prep. You can make a large batch, refrigerate it, and heat up portions during the week. Just keep the fresh toppings separate until serving.
