Print Recipe

A rich, cheesy, low-carb cauliflower gratin that’s creamy inside, crispy on top, and perfect as a healthy side dish for ham, roast dinners, or cozy weeknight meals. This one-pan keto-friendly recipe hits all the comfort food notes without the carbs.

Ingredients

Scale

  • 1 large head of cauliflower, cut into florets

  • 1 cup heavy cream

  • 1 ½ cups shredded sharp cheddar cheese

  • ½ cup grated parmesan cheese

  • 3 oz cream cheese

  • 2 garlic cloves, minced

  • 1 tsp Dijon mustard (optional, but adds great flavor)

  • Salt and pepper, to taste

  • 1 tbsp olive oil or melted butter (for roasting)

  • Optional topping: crushed pork rinds or 2 tbsp almond flour

  • Optional pinch of ground nutmeg

Instructions

  1. Preheat oven to 400°F (200°C).

  2. Toss cauliflower florets with olive oil, salt, and pepper. Spread on a baking sheet and roast for 20–25 minutes, until golden and just tender.

  3. In a saucepan over medium heat, warm the heavy cream. Add cream cheese and stir until melted and smooth.

  4. Add garlic, Dijon mustard, a pinch of salt and pepper. Stir in cheddar cheese and half the parmesan. Cook until creamy and smooth.

  5. Lower oven temp to 375°F (190°C). Transfer roasted cauliflower into a baking dish. Pour cheese sauce over and gently mix to coat.

  6. Sprinkle remaining parmesan and any optional toppings on top.

  7. Bake for 20–25 minutes, until bubbly and golden. Let sit for 5–10 minutes before serving.

Notes

  • For extra crunch, sprinkle crushed pork rinds on top before baking.

  • Want more flavor? Add caramelized onions or diced jalapeños.

  • Can be made ahead and reheated. Tastes even better the next day.
