This Shrimp and Broccoli Alfredo Bake is the ultimate comfort food that pulls together tender shrimp, bright broccoli, and pasta, all wrapped up in an ultra-creamy homemade Alfredo sauce. Baked until bubbly and golden, this casserole brings everyone to the table with its irresistible aroma and cheesy, satisfying goodness. It has become my go-to when I want something both impressive and feel-good on busy weeknights or for a cozy Sunday dinner.
The first time I made this, my kids went back for seconds before I finished serving myself. Now, it is a must anytime shrimp are on sale or I want to celebrate something small at home.
Ingredients
- Large shrimp: Ensure firm texture with a sweet and delicate flavor Choose fresh or thawed frozen shrimp that have no fishy odor
- Broccoli florets: Bring verdant crunch and balance the richness Look for bright green broccoli without yellowing
- Garlic and onion: Give aromatic warmth enhancing the sauce Use fresh for best results
- Penne or fettuccine: Provide shape that holds sauce beautifully Go for bronze-cut pasta if available for a toothsome bite
- Heavy cream: Forms the velvety Alfredo base Use full fat for the silkiest texture
- Grated Parmesan cheese: Delivers sharp nutty flavor Buy a wedge and grate yourself for maximum flavor
- Shredded mozzarella cheese: Melts into stringy richness Choose low moisture for best melting
- Unsalted butter: Adds creamy body to the sauce Select European-style for richer depth if possible
- Black pepper and nutmeg: Offer spicy subtlety and warmth Freshly ground is worth the extra touch
- Salt: Essential to balance flavors Try sea salt for brightness
- Fresh parsley: As a finishing touch gives color and a fresh contrast Use flat-leaf parsley for best flavor
Instructions
- Prep the Oven and Dish:
- Preheat your oven to 375 degrees Fahrenheit or 190 Celsius and make sure to generously grease a 9 by 13 inch baking dish so nothing sticks and cleanup is easy
- Cook the Pasta:
- Bring a large pot of salted water to a rolling boil then drop in your pasta Cook until just al dente so it can soak up sauce in the oven without getting mushy Drain well and set aside
- Sauté Aromatics:
- Heat butter in a large skillet over medium heat Add chopped onion and minced garlic Stir and gently cook for about two minutes until everything smells sweet and looks translucent This step builds the foundation of your sauce
- Cook the Shrimp:
- Add the peeled shrimp to the skillet in a single layer Cook just until pink flipping them once to avoid overcooking which keeps them juicy Remove shrimp and set aside for later
- Sauté the Broccoli:
- Add broccoli florets to the same skillet Sauté for two to three minutes until they brighten in color and turn just fork tender This keeps their crunch and vibrant green hue
- Make the Alfredo Sauce:
- Pour heavy cream into the skillet and bring to a gentle simmer whisking often Stir in Parmesan and mozzarella cheese little by little until the sauce is creamy and smooth Season with salt pepper and nutmeg if using Taste and adjust seasoning as needed
- Assemble the Casserole:
- Gently toss the cooked pasta broccoli and shrimp into your Alfredo sauce Stir until everything is evenly coasted and well combined
- Transfer and Top:
- Spoon the mixture into your greased baking dish Spread to an even layer and sprinkle three quarters of a cup grated Parmesan cheese evenly across the entire top for a golden cheesy crust
- Bake Until Golden:
- Place the baking dish uncovered in the oven Bake for twenty minutes or until the cheese topping is bubbling and a light golden brown in spots
- Finish and Serve:
- Remove from oven and let rest for five minutes so the sauce thickens slightly Sprinkle fresh parsley over the top for a touch of color Slice and serve piping hot

My favorite part of this dish is the Parmesan cheese It melts into the sauce and then forms a golden crust on top reminiscent of special Sunday dinners at my grandmother’s house when she would always offer just one more scoop.
