Prep and Cook Time
Readiness: 15 minutes | cooking: 35 minutes | Total: 50 minutes
Yield
Serves 4 hearty portions
Difficulty Level
Easy – perfect for weeknight dinners or a cozy weekend meal
ingredients
- 3 cups cauliflower florets, raw, chopped (substitute for traditional noodles)
- 2 (5 oz) cans tuna, drained and flaked, packed in water
- 1 cup shredded sharp cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup sour cream, full-fat for creaminess
- 1/2 cup mayonnaise, use olive oil-based for a healthy fat boost
- 1/2 cup chopped celery, for crunch and freshness
- 1/4 cup chopped green onions, mild onion flavor
- 1/2 cup mushrooms, sliced thinly (optional, for umami depth)
- 2 cloves garlic, minced
- 1 teaspoon Dijon mustard, for a tangy kick
- Salt and freshly cracked black pepper, to taste
- 1 tablespoon olive oil or avocado oil
- 1/2 cup crushed pork rinds, for a crunchy, low-carb topping
Instructions
- Preheat your oven to 375°F (190°C) and lightly grease a 9×9 inch baking dish.
- Steam the cauliflower florets until just tender, about 7-8 minutes, then drain thoroughly to remove excess moisture to avoid sogginess.
- In a medium skillet, heat olive oil over medium heat and sauté the minced garlic and mushrooms until golden brown, about 5 minutes, stirring occasionally to prevent sticking.
- In a large bowl, combine the steamed cauliflower, sautéed mushrooms and garlic, tuna, celery, green onions, cheddar cheese, sour cream, mayonnaise, and Dijon mustard. Stir gently to blend all ingredients evenly.
- Season generously with salt and black pepper to enhance all the flavors.
- Transfer the mixture into the prepared baking dish and sprinkle the crushed pork rinds evenly on top for a crispy crust.
- bake uncovered for 25-30 minutes or until the casserole is bubbly and the top is golden brown.
- Remove from the oven and let it rest for 5 minutes before serving to allow the flavors to unify and the texture to set perfectly.
Tips for Success
- cauliflower Prep: Pat steamed cauliflower dry using a kitchen towel or cheesecloth to prevent excess water from making the casserole watery.
- Tuna Choice: Opt for wild-caught tuna packed in water for a fresh flavor and a cleaner taste.
- Mayo Alternatives: If you prefer, Greek yogurt can substitute mayonnaise for a tangier, protein-enriched twist.
- Make-Ahead: Assemble the casserole in advance, cover, and refrigerate for up to 24 hours before baking for ultimate convenience.
- Vegetable Variation: Swap mushrooms for spinach or kale for added greens.
