Cheesy Keto Taco Casserole Recipe

Cheesy, scoopable, and endlessly decadent; this keto taco casserole recipe will be your new favorite Tex-Mex recipe for meal prep. Casseroles are the best way to prepare a flavorful and easy low-carb one-pan meal, setting you up for a quick lunch or dinner throughout your week.  

Anatomy of A Healthy Keto Casserole

Casseroles are by far one of the most underutilized ways to meal prep. They are hearty, comforting, and usually easy to prepare because all you have to do is mix everything into a baking dish and cook it! 

This Tex-Mex inspired low-carb taco casserole recipe utilizes ground beef, an array of seasonings and spices, along with vegetables and melted cheese to create a filling meal perfect for any day of the week. 

But preparing a keto-friendly taco-inspired casserole isn't the only way to make a casserole recipe; there are endless flavor combinations for you to mix and match. A normal, aka high-carb casserole, is usually prepared with protein, starch, sauce, vegetables, and cheese. The starch in these recipes is typically used to bind ingredients together. These could be ingredients like flour, potato, pasta, or a crunchy topping such as tater tots or bread crumbles. 

When it comes to creating a keto version, swap out starchy vegetables for low-carb vegetables, and feel free to double up on the meat! You'll still be able to create a delicious topping utilizing cheese, cauliflower rice, or even crushed pork rinds. 

The anatomy of a healthy keto casserole can be broken down as follows:  

  • Protein: From bacon to breakfast sausage, you can choose any kind of meat you'd like when making a casserole. Ground beef, turkey, chicken, shredded chicken, etc. Any of these options can be mixed with other ingredients to prepare a casserole. Eggs make a great base for breakfast casseroles and can be added to this recipe or any recipe utilizing another kind of meat. If you are vegetarian feel free to substitute a meat alternative such as beyond beef or tempeh. Whatever you choose be sure to use high-quality proteins such as grass-fed or organic meats and/or eggs. 
  • Low Carb Vegetables: If you are following a keto diet opt for non-starchy veggies first like spinach, kale, zucchini, broccoli, or cauliflower. When cooking these kinds of vegetables, these tend to release liquid helping the casserole stay moist. This is where you can multitask for your weekly meal prep; if you know you're going to purchase some zucchini for your casserole, chop up extra and set it aside to use for a quick stir fry later in the week.  
  • Dairy (cheese): Any kind of cheese works well in a casserole, so your choice may be dependent on what you have available or what your flavor combination is (i.e. Spanish style vs Italian inspired). Some popular cheese options: American, goat, Swiss, Monterey jack, cottage cheese, cheddar, and feta. Mix in a bit of cheese to the casserole base and the top of the top for a melty layer of cheesy goodness. 
  • Sauce: This can refer to any kind of liquid you add to the casserole. Stock, wine, vegetable juice, salsa, marinara etc., can all be used to add flavor and help create a symphony of flavor in your casserole recipe. 
  • Herbs and Spices: Don't forget that you can open up your spice cabinet or pick up some fresh herbs. Dried rosemary, thyme, basil, and parsley can be easy ways to add flavor to your casserole, or opt for chopping up some fresh herbs like cilantro, dill, or chives! Other dried spices that add some flair and flavor: coriander, cumin, black pepper, curry powder, sage, and oregano.
  • Creative Seasonings: There are plenty of other creative ways to change up the flavors in your casserole recipes. Purchase a can of sundried tomatoes in oil and chop them up! Other easy add-ins could be olives, roasted red peppers, pesto, and tapenade!
