Instructions
Preheat the oven to 375°F (190°C).
Heat olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3-4 minutes until translucent.
Add the minced garlic, cauliflower, broccoli, and celery to the skillet. Cook for 5-7 minutes until the vegetables are tender but still slightly crisp.
In a large mixing bowl, combine the drained tuna, sautéed vegetables, shredded cheddar cheese, shredded mozzarella cheese, cream cheese, heavy cream, grated Parmesan cheese, Dijon mustard, dried thyme, paprika, salt, and black pepper. Mix well until fully combined.
Transfer the mixture into a greased 8×8-inch baking dish and spread evenly.
Bake uncovered for 25-30 minutes until the casserole is bubbly and the top is golden brown.
Remove from the oven and let it rest for 5 minutes before serving.
Garnish with chopped fresh parsley and serve warm.
