Taco night is a big deal in my household. We all have our own favorite taco recipe, and one of my favorite things to do is set up a taco bar for everyone to assemble their own.
But what's even easier, and a recipe we all love, is this taco casserole recipe. Made using ground beef seasoned with homemade taco seasoning, cheese, and favorite taco mix-ins, this is a truly delicious taco bake!
Here's what makes my recipe for taco casserole so special:
- It uses low-carb ingredients, like red bell peppers (source) and avocado (source).
- The taco seasoning is homemade - and even more flavorful than what you would get in a packet!
- None of the ingredients contain gluten, as long as you use my homemade taco seasoning.
- Best of all: it's delicious!
My whole family loved it.... I also loved the home made taco seasoning.

One of my secrets to making the best beef taco casserole is to use homemade taco seasoning. Something that always frustrates me about different taco seasoning mixes is how there's always a little something I'd like to adjust about them - and so many of them add in flour for no good reason!
Making homemade taco seasoning is the easiest way to get all the flavors you love into one simple blend. It's simple to do and so worth it! You can use store-bought taco seasoning, but if you have the necessary spices on hand, I recommend making it yourself.
How to Make Taco Casserole Keto
- Preheat the oven to 350°F. Spray an 11 x 7-inch pan with cooking spray. Cook ground beef in a large skillet over medium heat for 10-12 minutes until browned.
- Add pepper and onion and saute for 5 minutes until softened.
- Add taco seasoning, diced tomatoes and green chilies, and water, and simmer over medium heat for about 5 minutes.
- Spread taco meat in the bottom of the oiled casserole dish.
- In a bowl, whisk eggs, milk, and sour cream together.
- Spread over the beef mixture and top with shredded cheese.
- Bake for 30 to 35 minutes until the eggs are firm. Let cool for 10-15 minutes, then top with jalapenos and avocado. Serve and enjoy!
Keto Casserole Recipe Tips
- There is no need to drain the beef unless you find it has too much excess grease. If you do drain it, make sure to do so before seasoning, so no flavor is lost.
- I enjoy shredded cheddar the most with this dish, but you can use any cheese that melts well, like Colby Jack, Monterey Jack Cheese, or a Mexican shredded cheese blend.
Keto Casserole Recipes Toppings
- Avocado
- Tomatoes
- Jalapenos
- Extra cheese
My family's favorite toppings for this easy taco casserole recipe are exactly what you'd use for tacos in shells, like sour cream, guacamole, salsa, sliced green onions, and shredded lettuce! I personally love avocado and tomato slices for freshness, and always enjoy jalapenos for a little extra spice.
Pico de gallo, or simply cilantro, would also be a great addition. If you're not concerned about added carbs, you can also add fresh corn, black olives, black beans, or even a small serving of Mexican rice on the side.
Make-Ahead Instructions
- Follow steps 1-4 to assemble the beef and vegetable taco filling in a baking dish.
- Let it cool, then cover tightly with aluminum foil or plastic wrap and store in the refrigerator for 1-2 days. Alternatively, wrap it tightly in foil and store it in the freezer for up to 3 months.
- To finish the dish, make the dairy topping just before you plan to bake it.
- Bake it normally out of the refrigerator. If baking out of the freezer, let it thaw in the refrigerator overnight first and add some time to the baking time until heated through (the easiest way to check is with an instant read thermometer).
Storing Leftovers
Leftover taco casserole will last up to 3-4 days in the refrigerator in an airtight container, or in the freezer for up to 2 months.
Keto Taco Casserole FAQ
Shredded cheddar is our cheese of choice for this recipe. You can also use a shredded Mexican cheese blend, Colby Jack, or your favorite shredded cheese that melts well.
You can use other meats to make taco casserole, if you like, such as leftover shredded chicken or ground turkey. Keep in mind, ground turkey takes longer to cook than beef.
Add a little spice by giving it a dash of hot sauce or by adding additional jalapenos.
Avoid adding jalapenos and use less red pepper flakes in the seasoning (or leave them out entirely).
