Cheesy Tuna, Broccoli and Cauliflower Casserole

When I was a kid, one of my favorite dishes my mom would often make was tuna noodle casserole. It consisted of noodles, canned tuna, and a couple of cans of cream of mushroom soup. It was creamy and salty and truly comfort food.

This keto-friendly recipe, packed with nutrient-dense veggies, was inspired by this recipe by Catherine Jarret on Butter + Brie that matched ingredients I had on hand. I tweaked it a bit and it turned out to remind me of that childhood favorite.

6 ounces (168 g) cream cheese

1 cup grated Parmesan cheese

1/4 cup heavy cream

3/4 teaspoon sea salt

1 teaspoon ground black pepper

1/2 teaspoon garlic powder

1/2 teaspoon onion powder

4 cups (300 g) broccoli florets

3 cups (300 g) cauliflower florets

4 cans tuna, packed in water, drained

  2. In a small bowl, mix the cream cheese, mayo, Parmesan, cream, salt, pepper, garlic powder, and onion powder together.
