• Large mixing bowl
• 1 1/2-quart casserole dish (ungreased)
• Small bowl for mixing topping
• Spoon or spatula for stirring
• Oven mitts for safe handling

Possible Ingredient Additions and Substitutions

Additions:

• Cheese lovers: Add 1/2 cup shredded cheddar or Parmesan to the casserole mixture for extra creaminess.
• Herbs and spices: A sprinkle of garlic powder or dried thyme can enhance the flavor profile.

Substitutions:

• Gluten-free: Use gluten-free pasta and breadcrumbs.
• Dairy-free: Swap out the cream of mushroom soup and milk for plant-based alternatives, like coconut cream or almond milk.

Step-by-Step Instructions

🔵 1. Preheat and prepare the pasta.
Preheat your oven to 350°F. Bring a medium pot of water to a boil, and cook the penne pasta according to the package instructions, using the minimum cooking time. Drain and set aside.

🔵 2. Combine the casserole base.
In a large mixing bowl, combine the cream of mushroom soup, milk, drained tuna, and sliced mushrooms. Stir well to ensure everything is evenly coated. Fold in the cooked pasta gently to avoid breaking the noodles.

🔵 3. Layer in the casserole dish.
Transfer the mixture into an ungreased 1 1/2-quart casserole dish, spreading it out evenly. Cover with aluminum foil to prevent drying out during the initial bake.

🔵 4. Bake the base.
Place the casserole dish in the preheated oven and bake for 20 minutes. This allows the flavors to meld and the sauce to begin bubbling.

🔵 5. Add the broccoli.
Remove the casserole from the oven. Carefully cut any large pieces of thawed broccoli into bite-sized chunks. Stir the broccoli into the casserole mixture, ensuring it’s evenly distributed.

🔵 6. Prepare the topping.
In a small bowl, mix the melted butter, panko breadcrumbs, and slivered almonds. This combination will create a crunchy, golden crust.

🔵 7. Finish baking.
Sprinkle the breadcrumb-almond mixture evenly over the top of the casserole. Return it to the oven, uncovered, and bake for an additional 30 minutes. The dish is ready when it’s bubbly around the edges and the topping is golden brown.

🔵 8. Serve and enjoy!
Allow the casserole to rest for 5 minutes after removing it from the oven. Serve warm, and watch it disappear as everyone comes back for seconds.

Suggestions on What to Serve with Tuna-Broccoli Casserole

Tuna-broccoli casserole is a complete meal in itself, but pairing it with complementary dishes can elevate your dining experience. Here are a few serving suggestions:

Side Dishes

• Fresh Green Salad: A crisp, leafy salad with a light vinaigrette balances the richness of the casserole.
• Garlic Bread: Toasted garlic bread or buttery dinner rolls make for a satisfying accompaniment.
• Roasted Vegetables: Oven-roasted carrots, zucchini, or asparagus add vibrant flavors and colors.

Beverages

• White Wine: A crisp Sauvignon Blanc or Chardonnay pairs beautifully with the creamy, savory flavors of the dish.
• Iced Tea or Lemonade: These refreshing beverages are perfect for a casual family dinner.

Storage and Reheating Tips

Storing Leftovers

• Refrigerator: Store leftover casserole in an airtight container for up to 3 days.
• Freezer: For longer storage, freeze portions in freezer-safe containers for up to 2 months. Thaw in the refrigerator overnight before reheating.

Reheating

• Oven: Place the casserole in a preheated oven at 350°F and heat until warmed through (15–20 minutes).
• Microwave: Transfer a portion to a microwave-safe dish and heat on medium power in 1-minute increments, stirring in between to ensure even heating.

Tips for Perfecting the Recipe

• Don’t Overcook the Pasta: Slightly undercook the penne to ensure it doesn’t become mushy during baking.
• Toast the Almonds: For an extra burst of flavor, lightly toast the slivered almonds before mixing them into the topping.
• Use Fresh Broccoli: While frozen broccoli is convenient, fresh broccoli steamed until tender-crisp can add more vibrant flavor and texture.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! Prepare the casserole up to the point where you add the breadcrumb-almond topping. Cover and refrigerate for up to 24 hours. When ready to bake, add the topping and extend the cooking time by about 10 minutes to account for the chilled ingredients.

What other proteins can I use instead of tuna?

Shredded chicken, cooked turkey, or even canned salmon work well as substitutes for tuna. For a vegetarian twist, consider adding chickpeas or lentils.

How can I make the casserole spicier?

Stir in a pinch of red pepper flakes or diced jalapeños to the casserole mixture for a spicy kick.

Is there a way to make this casserole healthier?

Yes! Use whole-grain pasta, reduced-fat cream of mushroom soup, and unsweetened almond milk to lighten the dish. You can also add extra veggies like bell peppers or spinach for more nutrients.
