Cheesy Keto Ground Beef Casserole With Spinach and Mushrooms

Keto Ground Beef Casserole 

This recipe is a tasty way to use up ground beef. It has a thick and creamy texture with a mild flavor – so it is perfect for picky eaters or families with kids. You can also confidently take it to a cookout or pot luck and know that everyone is going to eat it up!

As long as they aren’t lactose intolerant, they will love it!

This hearty casserole will fill everyone up! All the dairy and cheese make it taste super-rich. It doesn’t take much of this casserole to fill you up.

Not only is it hearty, but it is budget-friendly too. The most expensive ingredient in it is ground beef. To save money on beef, I buy it in bulk and then separate it into one-pound sections and freeze it.

This casserole uses about 1 1/2 pounds of ground beef, but you can probably get away with just using one pound. 

Ground Beef Spinach Casserole 

Spinach is the perfect vegetable to use in cheesy casseroles because it wilts and has a very mild taste. Try to add a little bit of kale to it too.

The kale will give it a bolder taste and make it even healthier. Don’t worry if you don’t like kale, spinach is plenty healthy by itself. It is really high in iron, vitamin A, and vitamin C. 

Ground Beef Spinach Bake Low Carb 

Make a huge batch of it and save some back for your meal prep the rest of the week. I love how it tastes when you heat it back up! Store leftovers in airtight food storage containers and then keep it in the refrigerator. It will stay fresh for up to 5 days.

After five days, the taste and texture will start to deteriorate. 

There are lots of ways that you can customize this casserole and make it taste different each time. Use a different type of cheese – pepper jack is slightly spicy. If you want to make it have a southwest flair, add some salsa on top before you eat it.

The options are endless! 

Spinach Mushroom Casserole 

You can also turn this into a meatless meal. Just double the number of mushrooms and spinach and add more vegetables. Zucchini and squash will taste perfect mixed in!

Or, use a different type of meat. Ground turkey and chicken have a lot less flavor, so if you use them, I suggest adding more garlic and salt. For more flavor, use some ground sausage. 

The only spices I used in this casserole is basil and garlic. If you want it to have more flavor, I suggest adding some parsley, oregano, and marjoram. Some red pepper flakes will add an undertone of heat. 

What To Serve With Beef Casserole 

Since this casserole has lots of Italian flair to it, I suggest making some low-carb bread to go with it. My kids love my keto garlic knots. Or, make some crispy low-carb garlic toast. Roast or steam some veggies or add a chopped salad and you have a really quick and easy feast ready for your entire family!
