The Ingredients
Here’s a straightforward list of what you’ll need to whip up this creamy casserole:
- 1 cup heavy whipping cream
- 2 (4.5-ounce) cans wild-caught tuna, drained well
- ½ teaspoon freshly ground black pepper
- 8 ounces full-fat cream cheese, softened
- 1 pound fresh broccoli florets (or 16 ounces pre-cut florets)
- 2 tablespoons unsalted butter, melted
- 1 tablespoon grated Parmesan cheese
- 2 cloves fresh garlic, minced or crushed
- ¼ teaspoon crushed red pepper flakes
- ½ teaspoon fine sea salt, or to taste
- 1 cup shredded sharp cheddar cheese
- 1 teaspoon Italian herb blend
- ½ cup shredded mozzarella cheese, for topping

Instructions
Let’s roll up our sleeves and get started! Here’s how you prepare this tuneful dish:
Step 1: Preheat Your Oven
Set your oven to 350°F (175°C). The anticipation builds as we prepare to bake this casserole.
Step 2: Prepare the Broccoli
While the oven warms up, bring a pot of salted water to a boil. Drop in the fresh broccoli florets. Cook for about 3-4 minutes until they’re bright green and just tender. Don’t overdo it; they’ll cook more in the oven. Drain and set aside.
Step 3: Mix the Creamy Base
In a large bowl, combine the softened cream cheese and heavy cream. Stir until smooth. Add in the melted butter, garlic, black pepper, sea salt, and crushed red pepper flakes. Mix thoroughly, ensuring a silky consistency.
Step 4: Combine Tuna and Cheese
Next, fold in the canned tuna and Parmesan cheese. Gently stir so as not to break the tuna too much.
Step 5: Combine All Ingredients
Now, gently fold the cooked broccoli into the creamy mixture. Next, add in the Italian herb blend and stir until everything is evenly combined.
Step 6: Add a Cheese Layer
Transfer the mixture into a greased 9×13-inch baking dish. Top it with shredded cheddar and mozzarella cheese.
Step 7: Bake Away
Place the casserole in the preheated oven. Let it bake for about 25-30 minutes, until the cheese is bubbly and golden brown.
Step 8: Cool and Serve
Once it’s done, remove the dish from the oven and allow it to cool for a few minutes before serving. This dish pairs beautifully with that garlic bread or a crisp side salad.
Notes
Tip 1: Want more texture? Top with breadcrumbs combined with a little melted butter before the cheese layer for extra crunch.
Tip 2: For a healthier twist, use Greek yogurt in place of half the cream cheese.
Tip 3: Mix in some cooked pasta for a heartier meal.
Tip 4: Leftovers? This casserole keeps well in the fridge and can be reheated easily.
Tip 5: Feel free to switch cheeses. Gruyère or fontina add a creamy richness.
