If you’re on a tight schedule and need a weeknight meal, but still want something healthy and delicious, ditch your taco shells and make Low Carb Keto Taco Casserole!kinda like a slow cooker Keto Chili, but each bite is infused with rich taco flavor. Since it’s a Crock Pot Taco Casserole, the slow cooker does all the work – but if you want to make it last minute, I’d go with the oven below.

Ingredients and Substitutes

This section explains how to choose the best ingredients for a low-carb taco casserole, the role each ingredient plays in the recipe, and substitution options.For measurements, see recipe card below.

• avocado oil – For frying ground beef. Use any neutral cooking oil you like.
• Ground beef – I usually use 85/15 grass fed ground beef from here, but either will do.If ground beef is not your thing, you can easily use ground turkey, ground chicken or even Mexican Chorizo.
• taco seasoning – You can’t have a tomato taco casserole without taco meat, and that means taco seasoning!I do it myself Taco Seasoning Mix, but you can also use store-bought mixes. Note that my seasoning has salt in it, but if yours doesn’t, add 1 1/2 to 2 teaspoons of salt.
• bell pepper – Use orange, yellow or red bell peppers for color variety.
• onion – I used yellow onions, but white or red onions would work too.
• Green Chili Diced Tomatoes – Chili will add a little heat. If you prefer a milder Mexican tomato casserole, substitute regular diced tomatoes for a can or two. Just be mindful of the size – the ones with chiles are 10 oz each, while the ones without are usually 14.5 oz, and your recipe will call for a total of 20 oz whether you use with or without chili.
• cheddar cheese – Use a good quality melted cheese for the perfect finish. Substitute Mexican blend cheese, mozzarella, Colby jack, or Monterey jack if you prefer.
