With the bold flavors of garlic, parmesan, and bacon this easy keto casserole will please the most reluctant low carb eater. My Chicken Bacon Spinach Casserole is great when you are pressed for time. It is easy, flavorful, and can be made ahead. You can even make it in a crockpot. This easy keto casserole recipe is low carb, keto, gluten-free, grain-free, sugar-free, and Trim Healthy Mama friendly.
I've made this keto casserole so many times over the last few months it's amazing my kids haven't complained. But they still love it. This is the only way to get some of them, or all of them, to eat spinach. When I'm craving a little rich and creamy comfort food this is one of my go-to keto casserole recipes.
How to make a keto casserole
The simplest way to make any casserole keto-friendly is to leave out the starches. Most regular casseroles call for fillers like rice, pasta, or beans. In my low carb casseroles, I use proteins, vegetables, and fat. No starches.
How to make a casserole in a crockpot
It isn't hard to convert this to a slow cooker recipe. There are just three steps to making a chicken casserole in a crockpot instead of your oven.
- Cook the chicken in the crockpot. It is very important not to OVERCOOK the chicken or you will have a dry casserole. Cook chicken breasts on low for 2.5 hours. Add a little chicken broth, butter or oil, and salt and pepper before cooking.
- DRAIN the cooking liquid. Cut up the chicken.
- Proceed with the rest of the casserole recipe. This time just cook it in the crockpot until it is hot.
The most important step is draining the cooking liquid. If you don't do this you will end up with soup instead of a casserole.
What ingredients are in the sauce?
My typical sauce base for casseroles is cream cheese, mayo, and sour cream. This is how I can get a smooth and rich sauce without using any cans of condensed soup.
Chicken, chicken, and more chicken
We eat a lot of chicken. It is very budget friendly and easy to cook. You may remember me getting excited when my husband brought me home a two-pound bag of shrimp.
I was slightly less excited when he brought home 12 pounds of chicken breast because the freezer was packed after my Costco trip the day before. I managed to squeeze one pack in any way and we cooked the rest.
This casserole was invented about halfway through our chicken week when I just needed something that tasted less like chicken. So, in other words, it needed bacon. This Chicken Bacon Caesar Casserole has already gotten rave reviews from everyone who has tried it.
What else is in this keto chicken casserole?
This is very similar to my Chicken Bacon Ranch Casserole. If you've tried that one and liked it there is high probability you will like this one too. Instead of dried herbs, there is parmesan cheese and roasted garlic powder. Instead of cheddar, there is mozzarella. But there is always bacon.
More keto casserole recipes:
- 8 oz cream cheese softened
- 4 oz sour cream
- 4 oz mayo
- 2 teaspoon roasted garlic powder (this is worth the investment, the flavor is amazing!)
- 2 teaspoon dried minced onion
- 2-2.5 lb cooked chicken , cubed
- 12 oz bag frozen spinach , thawed and drained
- 1 cup grated parmesan cheese
- 4 slices crisp cooked bacon or ¼ cup bacon crumbles
- 2 oz shredded mozzarella
- Preheat oven to 350 if baking immediately. Or you can prep ahead and keep in the refrigerator for a day or two.
- Combine cream cheese, sour cream, mayo, and spices and mix thoroughly. I do this first in a big metal bowl.
- In the big bowl combine the cream cheese mixture you just made with the chicken, spinach, parmesan cheese, and ½ the bacon and mix well.
- Dump into a 9x13 baking dish sprayed with cooking spray. Sprinkle remaining cheese and bacon on top.
- Bake until hot about 35 minutes.
