Meatloaf is always a good idea, and it doesn’t get much better than this Keto Meatloaf! Cheesy, gooey, and flavor-packed, this is comfort food at its best. The cayenne pepper gives this a nice kick - if you are serving this to small children you may want to either reduce or eliminate it.

You are going to love this Keto Meatloaf. It's cheesy, gooey goodness is home cooking at its best.
I recommend serving this with a side of Low Carb Cauliflower Mash. The duo is just perfect when you are craving meat and potatoes.
Ingredient Notes
- Ground Beef: You could use ground beef or ground turkey if you prefer.
- Onion: I like a yellow or white onion in meatloaf, but you could use red onion if you prefer.
- Parmesan Cheese: Grating your own provides the most flavor and also helps to avoid the additives that come in pre-grated cheese.
- Mozzarella Cheese: Provolone or montery jack would also work well in this recipe.
Sauce
- Tomato Sauce: Keep this low-carb by avoiding brands that contain added sugar. Make sure you check the label!
- Liquid Smoke: You can omit if you don't have it.
Frequently Asked Questions
Can I Use Regular Ketchup in Place of the Topping?
That depends on your diet goals! If you are on Keto or a very strict low-carb diet, you are going to find that most traditional ketchups have far too much sugar in them to work for you.
Will My Meatloaf Fall Apart without Breadcrumbs?
Although it will not hold together quite as well as it would with breadcrumbs, the eggs do a nice job of keeping this meatloaf together. You do want to let the meat cool a bit before cutting. This will help it to stay together.

Cant buy liquid smoke in uk! Will it be fine without.
Wendy Polisi says
It sure will! If you want a smoky flavor, you could always add additional smoked paprika.

Recipe is great. My family members are fans of mustard smeared on top and sides of meatloaf prior to baking. To please my family I used simply mustard and we loved it. Thank you for the recipe.
Wendy Polisi says
So glad you liked it! I have never had meatloaf with mustard - I am so going to try that.
