Keto Taco Ground Beef Casserole Ingredients

For this taco ground beef casserole I used ground beef, lots of spices, cauliflower, peppers, cream cheese, cheddar cheese and pasta sauce . I used a lot of cauliflower and this was to give it bulk with out the carbs. Also cauliflower has a very neutral flavor and takes on the Mexican spices nicely.

The cream cheese and cheddar cheese make a nice queso type sauce when mixed with pasta sauce and Mexican spices. I used Aldi Specialty Selects Marinara sauce because it only has 8g net carbs in 1 cup.

You could always substitute jar salsa if you have it and 1 cup of salsa is equal or less than 8g net carbs. I didn't have any on hand so I use the marinara and with the spices it was great.

Let's Make This Taco Casserole

First thing you want to do is mix all the spices together . This is a bit spicy but it's not hot spicy. Next you brown the ground beef in a skillet along with half of the spices.

Once that is done the rest is easy. Above you can see the steps. The bottom layer is the raw chopped vegetables then scatter the chunks of cream cheese. Next top that with 1/2 of the cheddar cheese and marinara sauce that has been mixed with the other half of the spices. Lastly pour the ground beef into the crock and sprinkle the rest of the cheddar.

You can cook this on high for 4 hours or low for 8 hours . This will depend on how your slow cooker works. However make sure to mix the casserole together before serving. You want the sauce to cover all the vegetables and meat.

Recipe Tips & Notes

This recipe uses a lot of spices but is not hot spicy. You can use less of the spice mix if you wish but it might take away from the flavor.
When you brown the meat you just want to get it cooked but not over done. So just as it's changing from pink to brown it should be done.
Layer the casserole with the vegetables on the bottom since they are raw.
Also make sure to mix the casserole before serving so the cheesy sauce combines with everything.
The timing on the casserole may vary depending on your slow cooker. But since the meat is cooked it might not take as long as most slow cooker recipes.
