Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.
Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for 5-6 minutes, until tender but not mushy. Drain and set aside.
In a large skillet over medium heat, sauté the chopped onion and celery in a drizzle of oil for 4-5 minutes until softened. Add garlic and cook for another 1 minute, stirring constantly.
In a large mixing bowl, combine the drained tuna, sautéed vegetables, mayonnaise, sour cream, almond milk, lemon juice, Dijon mustard, salt, black pepper, and paprika. Mix until well incorporated.
Gently fold in the cooked cauliflower and 1.5 cups of the shredded cheddar cheese. Transfer the mixture to the prepared casserole dish, spreading it out evenly.
Sprinkle the remaining 0.5 cup of shredded cheddar cheese and the grated Parmesan cheese over the top of the casserole.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Remove from the oven and let it rest for 5 minutes before serving. Garnish with chopped parsley, if desired.
