Ingredients

  • 1 head cauliflower chopped into florets (about 5 cups)
  • 2 slices bacon chopped
  • 1 tablespoon olive oil
  • ¼ cup yellow onion diced
  • 3 garlic cloves minced
  • 1 cup almond milk or milk of choice
  • 2 tablespoons all-purpose flour or tapioca flour for gluten-free
  • 1 cup shredded cheddar cheese
  • 1 cup shredded parmesan cheese
  • ½ teaspoon salt
  • 2 tablespoons chives chopped

Instructions

  • Preheat the oven to 400°F (200°C).
  • In a large, deep skillet over medium heat, cook the chopped bacon until crispy. Remove with a slotted spoon and set aside, reserving the bacon grease in the skillet.
  • Bring a saucepan of water to a boil. Add the cauliflower florets and cook for 5 minutes. Drain and set aside.
  • Add olive oil, diced onion, and garlic to the skillet with the bacon grease. Sauté for 3–5 minutes, until the onion softens.
  • In a small bowl, whisk together the milk and flour until smooth.
  • Pour the milk mixture into the skillet. Bring to a low boil, just until the edges begin to bubble.
  • Stir in the cheddar, parmesan, and salt. Whisk until the cheese sauce is smooth and creamy.
  • Fold in the drained cauliflower until fully coated in the cheese sauce.
  • Transfer the mixture to an 8x8-inch baking dish. Sprinkle the cooked bacon evenly over the top.
  • Bake for 20 minutes.
  • Remove from the oven, sprinkle with chopped chives, and serve hot.

Notes

Use dairy-free milk for a non-dairy version.
Tapioca flour is an excellent gluten-free substitute for all-purpose flour.
Can be assembled ahead of time and baked before serving.
