Tips for the Best Keto Mac and Cheese

This is essentially perfect cauliflower mac and cheese, but there are things that can go wrong, gritty or grainy cheese sauce for example. So here are some tips to make your baked mac and cheese awesome.

  1. Cheese:  Grate your own cheese. Pre-shredded cheese is usually coated in anti clumping agents which prevent it from melting beautifully in your mac and cheese sauce.
  2. Add Cheese Off Heat: Be sure to add the cheese after you’ve removed the pan from the heat. If you add the cheese when it’s bubbling, it can cause it to break down and become gritty.
  3. Add it Slowly: Add the cheese slowly, about 1/2 cup at a time and stir till completely melted then add more. This helps retain a smooth velvety texture to your mac and cheese sauce.
  4. Bite Sized: Keep your cauliflower the same size for even cooking and in bite sized pieces. It will be easier to eat this incredible mac and cheese.
  5. Chill:  Placing the cauliflower in ice water will stop it from cooking so it doesn’t become too soggy or limp.
  6. Dry: Make sure the cauliflower dry. You may need to pat them dry with paper towels so you don’t have extra water in the cheese sauce.

Variations for Macaroni and Cheese

This cauliflower mac and cheese is completely customizable, and it will still be spectacular. Here are a few ways!

  • Cheese: You are not stuck with just cheddar as the only option, as great as it is. Mix it up with different combinations of cheeses. Monterey Jack, pepper jack, havariti, swiss, guyre, or colby all are fun to include or mix and match.
  • Topping:  If you like your mac and cheese with a little crunch on top, feel free to add a mixture of melted butter and bread crumbs, french fried onions or panko.
  • Add ins: You can mix up the veggies in this cauliflower mac and cheese if you desire. Add in broccoli, zucchini, peppers or mushrooms.
  • Meats: Give the mac and cheese some protein with ham, bacon or sausage.
  • Roast:  You can oven roast the cauliflower instead of boiling it if you prefer. Toss in some olive oil and cook on a cookie sheet at 400 degrees for 20-25 minutes or till done to your liking. Roasting it will give the cauliflower a bit of a crunch, so yummy!

Storing and Reheating Baked Mac and Cheese

Cauliflower baked mac and cheese is best eaten the day you make it. Unfortunately it does not freeze well, so I don’t recommend it. You can freeze it but the texture will be grainy and gritty. Not ideal for mac and cheese enthusiasts.

  • Store: Leftovers, if you have them, will store tightly covered in the fridge for up to 3-4 days.
  • Reheat: One of the best ways to reheat this cauliflower mac and cheese is in the oven. Place in the oven at 350 degrees for 10-15 min or till heated through. I’m often not that patient however, so if your like me reheat in the microwave till almost heated through. Then finish heating up in the oven for the last 5 minutes to help give it that bubbly crust on top.
  • Too Thick: If your mac and cheese sauce has thickened too much, add a little milk to thin it out.
