This Low-Carb Cauliflower Gratin with Sharp Cheddar and Parmesan is a recipe that has quite a few fans and it’s delicious, cheesy, and comforting and also ridiculously easy to make. There’s something so perfect about the combination of cauliflower + cheese; wouldn’t you agree?

This recipe is a close cousin to the Broccoli Gratin with Swiss and Parmesan that’s also one of my favorites (and something I’ve made over and over for Thanksgiving.)  Both of them are great as a cheesy side dish, but recently I ate the cauliflower for a low-carb main dish (kind of a mac-n-cheese wanna-be) and thoroughly enjoyed it as a meatless meal with a green salad on the side.

How to Make Low-Carb Cauliflower Gratin with Sharp Cheddar and Parmesan:

(Scroll down for complete printable recipe.)

  1. Cut a medium-sized head of cauliflower into bite-sized pieces; then cook the cauliflower in boiling water for 10 minutes.
  2. While cauliflower is cooking, mix together finely grated sharp cheddar cheese, mayo, sour cream, lemon juice, Dijon mustard, and pepper.
  3. When cauliflower has cooked ten minutes, drain well in a colander placed in the sink.
  4. After cauliflower drains well, place in baking dish that you’ve sprayed with non-stick spray or a little olive oil.
  5. Use a rubber scraper to spread the cheese mixture over the cauliflower.
  6. Sprinkle with Parmesan cheese and bake 25-30 minutes, or until cauliflower is bubbly and lightly browned on top.
  7. Yum! I’d love this for a meatless dinner or a cheesy side dish!

Low-Carb Cauliflower Gratin with Sharp Cheddar and Parmesan

Yield 6 servings
Prep Time 20 minutes
Cook Time 30 minutes
Total Time 50 minutes

Low-Carb Cauliflower Gratin with Sharp Cheddar and Parmesan can be a tasty side dish or a nice stand-in for Mac-n-Cheese.

Ingredients

  • 1 medium head cauliflower, cut into bite-sized pieces
  • 1 cup finely grated sharp cheddar cheese
  • 4 T mayo
  • 4 T sour cream
  • 1 T fresh squeezed lemon juice
  • 1/2 tsp. Dijon mustard
  • fresh ground black pepper to taste
  • 3 T finely grated Parmesan cheese

Instructions

  1. Preheat oven to 375F/190C.
  2. Cut cauliflower into bite sized pieces. (To avoid the little broken pieces of cauliflower all over the cutting board, cut through cauliflower stem, then pull apart the flower end.)
  3. Put cauliflower in a small pot, add water to cover by a few inches, then bring to boil and cook 10 minutes, or until cauliflower is just starting to get tender.
  4. Drain cauliflower into a colander placed in the sink and let it drain very well.
  5. While cauliflower cooks, stir together mayo, sour cream, lemon juice, Dijon mustard, and black pepper. Stir in finely grated sharp cheddar.
  6. Spray a large glass or crockery baking dish with olive oil or non-stick spray, then pour the well-drained cauliflower into the dish and spread out evenly.
  7. Use a rubber scraper to spread gratin mixture over the top of the cauliflower. (This is not a sauce that completely covers the cauliflower, more like a topping.)
  8. Sprinkle with Parmesan cheese and bake uncovered for 25-30 minutes, or until cauliflower is bubbling and lightly browned.
  9. Serve hot.
