Ingredients

  • 3 cups cauliflower florets

  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 2 cups milk
  • 2 cloves garlic, minced or 1 teaspoon garlic powder

  2. Steam or boil the broccoli and cauliflower until tender, about 4–5 minutes. Drain and set aside.
  3. In a saucepan, melt butter and whisk in flour to make a roux. Cook for 1–2 minutes.
  4. Gradually whisk in the milk and simmer until the sauce thickens.
  5. Stir in garlic, Dijon mustard (if using), salt, pepper, and most of the cheddar and Parmesan cheeses until melted.
  6. Mix the vegetables into the cheese sauce and transfer to the baking dish.
  7. Sprinkle with remaining cheese and optional breadcrumbs or crushed crackers.
  8. Bake for 20–25 minutes until bubbling and golden on top.
  9. Let cool for a few minutes before serving.

Notes

  • To make it gluten-free, use a gluten-free flour blend and gluten-free breadcrumbs.
  • Frozen vegetables can be used if thawed and drained well.
  • For a heartier dish, add cooked pasta, chicken, or ham.
  • Store leftovers in the fridge for up to 4 days.
  • Reheat in oven or microwave; add milk if sauce thickens.
