When you think about the ultimate comfort food, a warm casserole dish is probably somewhere on the list. Not only are these a delicious way to eat a comfort meal, but these dishes are also super convenient and easy to prepare, especially if you’re wanting to meal prep for a few days of cooking for more than just you. 

Think of lasagna, chicken pot pie, and shepherd’s pie. All great comfort foods. But all loaded with a ton of carbs. And when you’re on a fitness journey, you’re probably looking to stay within your diet, which means staying away from classic casserole dishes like these. However, a simple switch in ingredients can help you stick to your goals while also still bringing you the same amount of satisfaction and convenience that classic casserole recipes offer.

That’s why today I’m sharing a round up of low carb casserole recipes you would love that will hit all the spots. Hope you enjoy!

10 Low-Carb Casserole Recipes

Before we jump right into the recipes, let’s first talk about what a low-carb casserole is just be sure that we’re all on the same page.

What Is A Low-Carb Casserole

A classic casserole recipe is a one pan dish usually made with a pasta or rice base, any variety of meats or beans, and is typically loaded with cheeses and creamy sauces.

In a low carb casserole, the pasta and rice is usually replaced with a low carb base like cauliflower, broccoli, or zucchini alternatives. The meats in low carb casseroles are also typically lean proteins like chicken, beef, or fish and other ingredients used typically include healthy fats like avocado for example.

Low carb just means there is usually less than 45 grams of carbs per serving. Enjoy any one of these low carb casserole recipes below.

How To Make A Casserole Low Carb

Write down your favorite casserole recipes 

When you think of your favorite casserole dishes? What comes to mind? What ingredients do you typically need? Write down the recipe and highlight the ingredients that are high carb that may need to get switched out. This will help you make a low carb grocery list.

Switch up the ingredients

Replace your protein with lean protein like chicken, ground turkey, beef, and fish. Add avocado, and low carb cheeses like cheddar, Gouda, Parmesan, and cottage cheese. Check the labels on your creamy sauces or make your own with low sugar and carbs. This should help you with being able to measure the right amount of carbs, fats, and other nutrients that will go into the dish.

Eliminate the starch

When going for a low carb meal, opt for non starchy vegetables and skip the pasta and rice altogether. Look for cauliflower rice, zucchini noodles, and the like.
