This Keto Tuna Casserole is a low-carb, creamy, and cheesy dish perfect for those following a ketogenic diet. Combining tender tuna with nutrient-rich cauliflower rice and melted cheddar cheese, it’s an easy yet satisfying meal that can be prepared quickly and baked to golden perfection.

Ingredients

Protein & Dairy

  • 2 cans (5 oz each) tuna, drained
  • 1 cup heavy cream
  • 1 cup shredded cheddar cheese

Vegetables

  • 1 cup cauliflower rice (fresh or frozen)
  • 1/2 cup frozen peas (optional)
  • 1/4 cup diced onion
  • 2 cloves garlic, minced

Seasonings & Oil

  • Salt and pepper to taste
  • Olive oil for cooking

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) to ensure it reaches the ideal temperature for baking the casserole evenly.
  2. Sauté Aromatics: Heat olive oil in a skillet over medium heat. Add the diced onion and minced garlic, cooking until softened and fragrant, which usually takes about 3-5 minutes. This step enhances the flavor base of the casserole.
  3. Combine Ingredients: In a large mixing bowl, combine the drained tuna, cauliflower rice, heavy cream, frozen peas (if using), salt, and pepper. Carefully stir in half of the shredded cheddar cheese to incorporate the creamy texture and cheesy flavor.
  4. Assemble the Casserole: Pour the mixture into a greased 9×9-inch baking dish, spreading it evenly. Sprinkle the remaining cheddar cheese on top to create a delicious, cheesy crust when baked.
  5. Bake to Perfection: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese on top is melted, bubbly, and slightly golden. Remove from the oven and allow it to cool slightly before serving to set the casserole.

Notes

  • Using frozen peas is optional and can be omitted to reduce carbs further.
  • Fresh cauliflower rice can be used instead of frozen; just ensure it’s well-drained to avoid excess moisture.
  • For added flavor, consider mixing in some fresh herbs like parsley or dill.
  • Ensure the baking dish is greased well to prevent sticking.
  • This casserole can be portioned and stored in the refrigerator for up to 3 days.
