Description

Steamed broccoli and cauliflower are combined in a creamy cheese sauce with hints of savory bacon then baked until bubbly and brown. It’s like eating a loaded potato casserole but is much lower in carbs! You’ll only need 30-minutes to whip together this keto main dish.


Ingredients

  • 12 oz bag frozen cauliflower florets
  • 10 oz bag frozen broccoli florets
  • 4 bacon slices
  • 2/3 cup (160g) sour cream
  • 4 oz cream cheese, softened
  • 2 tbsp (30g) mayonnaise
  • 1/4 tsp garlic powder
  • 1/4 tsp pepper
  • 1/8 tsp onion powder
  • 1/8 tsp paprika
  • 1 1/2 cups (168g) shredded sharp cheddar cheese
  • 1/2 cup (56g) shredded mozzarella cheese
  • 2 tbsp finely chopped green onions

Instructions

  1. Place oven rack on middle rack, preheat oven to 450 degrees, and generously coat 8×8-inch baking pan in nonstick cooking spray.
  2. Microwave frozen cauliflower florets then frozen broccoli florets until tender, according to instructions on bags.
  3. While vegetables cook, in a large pan over medium heat, cook bacon until crispy. Transfer to paper towel-lined plate and crumble into pieces.
  4. In a small mixing bowl, mix together shredded cheeses. Then, in a separate mixing bowl, mix together sour cream, cream cheese, mayonnaise, and spices. Fold in steamed vegetables, half of the crumbled bacon, and ~1 cup of shredded cheese mixture.
  5. Transfer mixture to prepared baking pan and, using a rubber spatula, spread into an even layer. Sprinkle remaining shredded cheese mixture then remaining bacon crumbles on top.
  6. Cover pan with foil, transfer to oven, and bake for 12-15 minutes. Then, remove foil, move oven rack to top rack and turn on oven broiler. Broil casserole until cheese on top is bubbly and golden, about an additional 1-2 minutes, watching carefully to ensure it doesn’t burn.
  7. Remove pan from oven, allow casserole to cool slightly before garnishing with chopped green onions and serving.

Recipe Notes:

Making Recipe In Advance: You can complete steps 1 to 4 ahead of time. Refrigerate for up to 24 hours. Remove the dish from the refrigerator 30 minutes before baking. Cover it with aluminum foil and proceed with step 5 of the recipe to finish cooking.

Bacon Substitution: If you are vegetarian, feel free to leave out the bacon or use plant-based bacon.

Cream Cheese Substitution: You can use vegan cream cheese, or if you consume nuts, almond milk cream cheese at a 1:1 ratio should work.

Mayonaise Substitution: For this recipe, substitute mayonnaise for some extra sour cream at a 1:1 ratio.

Shredded Sharp Cheddar Cheese Substitution: White cheddar, Colby, or gouda make excellent options as well.

Shredded Mozzarella Cheese Substitution: Provolone or white cheddar cheese can be used in place of mozzarella.

Adding More Protein: You can consider including cooked chopped or shredded chicken. If chicken is used, you’ll need to adjust the nutrition facts.

Net Carbs: Per serving, loaded broccoli cauliflower casserole contains 5.8 grams of net carbs. The recipe, as written, yields 6 servings. Net carbs are calculated by taking total carbs, subtracting fiber, and subtracting sugar alcohols.

Refrigerator Storage: In an airtight container, store loaded broccoli casserole in the refrigerator for up to 3 days. For best results when reheating, put the casserole back in the oven at 325 degrees for about 15 minutes. If you want to reheat a single serving, pop it in the microwave for 1 to 3 minutes, depending on the wattage of your microwave.

Freezer Storage: Before freezing, portion out individual servings, then store them in an airtight container for up to 3 months. Let them thaw in the refrigerator overnight before reheating.
