Here it is! Mac and Cheese, one of the most beloved American classics, made low-carb. From all of the keto Mac and Cheese recipes I've ever made, this one is the best, and it's the perfect side dish for your Holiday table!
Recipe Tips for Keto Mac and Cheese
Making keto-friendly Mac and Cheese is easier than you think, and I listed a few options for each ingredient with alternatives and add-ins.
Best Alternative to Pasta in Mac and Cheese?
To keep the carbs low, we are replacing regular pasta with zero-carb shirataki penne, plus cauliflower for bulk and better texture and nutrition profile. Cauliflower works really well in this side dish casserole, plus it provides extra nutrients.
Make sure to prepare the noodles by the steps in this guide.:
- Drain and rinse the pasta
- Boil the pasta in water with vinegar
- Cook the pasta in a dry pan
These steps will only take a few minutes and are essential for improving the texture and removing any odor — the main reasons some people don't like eating konjac (shirataki) pasta.
And if you want to avoid shirataki pasta altogether, make this Keto Cauliflower Cheese instead.

Best Cheese for Keto Mac and Cheese?
You either use one type of cheese or a combination of two like I did. Gruyere is the best option for flavor, and mozzarella is a must for that perfect cheese pull. Don't use too much mozzarella though as it can make the cheese sauce too dry and stringy (See photo below which was made with 2 cups of mozzarella instead of 1 cup mozzarella + 1 cup gruyere).
You really can't go wrong with almost any cheese. Try cheddar, gouda or Emmental. Avoid pre-grated cheese as it's covered in starches and will make your sauce grainy. Always use freshly grated cheese when used in casseroles and bakes.
The cheese sauce in this recipe is based on my Keto Cheese Sauce which I modified for baking. To add flavor I used mustard powder and garlic but you can even add some herbs or use blue cheese to make a slightly different zero-carb pasta casserole.
Best Add-Ins to Keto Mac and Cheese?
You can keep this recipe simple and vegetarian or add any of your favorite proteins such as sliced chicken breasts, ground meat (pork, beef or turkey), chorizo or some crispy bacon. If you add any of these options, cook them on a lightly greased pan before combining with the remaining ingredients.
Want more flavor? Add any herbs or spices such as chives, onion powder, parsley, thyme, or even a pinch of turmeric or paprika for color.
Prefer more veggies? Add some steamed green peas, green beans, carrot or broccoli. I'm not sure I'd still call this a Mac and Cheese but it doesn't mean you can't experiment with flavors and textures!
What to Serve with Keto Mac and Cheese?
This Mac and Cheese is great on it's own or as a side. If you serve it as a side, you'll get 6 to 8 servings. If you serve it as a main course, it will be enough for 4 satisfying dinners.
As a side dish you can serve it with many dishes including Steak, herby Spatchcock Chicken, easy Southern Fried Chicken, 5-ingredient Wrapped Chicken Parcels, juicy Pork Belly or Crispy Lemon & Thyme Chicken.
