Shrimp and Spinach Casserole with Three-Cheese Blend

There’s something irresistibly cozy about a bubbling, golden casserole coming straight from the oven. When you combine tender shrimp, fresh spinach, and a luscious trio of ricotta, mozzarella, and Parmesan cheeses, you get a dish that’s both elegant and comforting — a little coastal flair meets classic home cooking.

Shrimp and Spinach Casserole with Three-Cheese Blend is a restaurant-worthy meal you can make easily at home. Every bite delivers creamy, cheesy richness balanced by the freshness of spinach and the subtle sweetness of shrimp. It’s the perfect dish for seafood lovers who crave something hearty without being heavy — luxurious but still easy enough for a weeknight dinner.

Inspiration Behind the Dish

This casserole was inspired by classic Italian-American comfort food — think baked ziti or lasagna — but with a lighter, seafood-centered twist. Instead of pasta, the base is shrimp and spinach, bound together with creamy cheeses that melt into a velvety sauce as it bakes.

The idea came from combining two favorites: garlicky sautéed shrimp and creamy spinach dip. Together, they transform into a decadent casserole that’s indulgent enough for guests but simple enough for a Tuesday night. The blend of ricotta, mozzarella, and Parmesan gives depth and richness, while breadcrumbs on top add the perfect crispy contrast.

If you’re craving something that tastes gourmet but doesn’t take hours to make, this is the dish for you.

Ingredients Breakdown

Servings: 4
Course: Main
Cuisine: American

Ingredients

• 1 pound shrimp, peeled and deveined
• 4 cups fresh spinach, chopped
• 1 cup ricotta cheese
• 1 cup mozzarella cheese, shredded
• 1 cup Parmesan cheese, grated
• 2 cloves garlic, minced
• 1 teaspoon olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon red pepper flakes (optional)
• 1 cup breadcrumbs

Each component plays a vital role: the shrimp provide sweetness and protein, the spinach adds freshness and color, and the three cheeses create that luscious, creamy texture that makes casseroles so satisfying. The breadcrumbs give the perfect finishing crunch.

Tools & Equipment Needed

Before you start, gather these kitchen essentials:

• Casserole dish (medium-sized, about 2 quarts)
• Skillet – for sautéing the shrimp and spinach.
• Mixing bowl – to combine the cheese mixture.
• Wooden spoon or spatula – for stirring.
• Measuring cups and spoons – for accuracy.
• Sharp knife and cutting board – for chopping spinach and garlic.
• Oven mitts – because that bubbling casserole will be piping hot!

Step-by-Step Instructions

Follow these simple steps to make the perfect Shrimp and Spinach Casserole.

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a medium casserole dish with olive oil or nonstick spray. This ensures easy cleanup and helps create that beautiful golden crust.

Step 2: Sauté the Garlic

In a large skillet over medium heat, add 1 teaspoon of olive oil. When warm, add the minced garlic and cook for 1–2 minutes, just until fragrant. Be careful not to brown the garlic — you want it aromatic, not bitter.

Step 3: Wilt the Spinach

Add the chopped spinach to the skillet. Sauté for 2–3 minutes, stirring occasionally, until just wilted. Spinach cooks down quickly, so don’t worry if the pan looks overflowing at first — it will shrink substantially. Remove from heat and set aside to cool slightly.

Step 4: Mix the Cheese Base

In a large mixing bowl, combine:

• 1 cup ricotta cheese
• 1/2 cup shredded mozzarella (reserve the other half for topping)
• 1/2 cup grated Parmesan (reserve the other half for topping)
• Salt
• Black pepper
• Red pepper flakes (if using)

Stir until smooth and creamy. This mixture forms the rich, flavorful base that ties the shrimp and spinach together.

Step 5: Add Shrimp and Spinach

Gently fold the shrimp and sautéed spinach into the cheese mixture. The shrimp will finish cooking in the oven, soaking up the garlic and cheese flavors for perfectly tender bites.

Step 6: Assemble the Casserole

Transfer the shrimp and cheese mixture into your prepared casserole dish, spreading it evenly with a spatula.

Sprinkle the remaining mozzarella and Parmesan cheeses over the top, then add the breadcrumbs in an even layer. This combination gives you that irresistible, golden crust once baked.

Step 7: Bake

Place the casserole in the preheated oven and bake for 25–30 minutes, or until bubbly and golden brown on top. The shrimp should be pink and opaque, and the cheese should be melted and slightly crisp around the edges.

Step 8: Rest and Serve

Let the casserole cool for 5–10 minutes before serving. This allows it to set slightly, making it easier to slice and serve. The aroma alone will bring everyone to the table!

Tips & Variations

• For extra crunch: Use panko breadcrumbs instead of regular ones for a lighter, crispier topping.
• Add pasta or rice: Mix in cooked penne or white rice before baking for a heartier meal.
• Vegetable swaps: Substitute kale, Swiss chard, or arugula for spinach for a slightly different flavor.
• Make it spicy: Increase the red pepper flakes or add a dash of cayenne for gentle heat.
• Low-carb version: Skip the breadcrumbs entirely or replace them with crushed pork rinds or almond flour.
• Add mushrooms: Sauté mushrooms with the garlic for an earthy boost of flavor.

Flavor Profile & Pairings

This casserole is the perfect harmony of creamy, cheesy, and savory flavors with a gentle seafood sweetness from the shrimp.

• Texture: The tender shrimp and velvety cheese filling contrast beautifully with the crisp breadcrumb topping.
• Flavor balance: Ricotta lends mild creaminess, mozzarella adds stretch and melt, and Parmesan gives a salty, nutty edge. The garlic and spinach provide freshness that brightens every bite.

Best Side Dishes

Serve this casserole with:

• A crisp green salad dressed with lemon vinaigrette
• Roasted asparagus or garlic butter green beans
• Crusty bread to scoop up the cheesy sauce
• A side of herbed couscous or rice pilaf

Each pairing complements the rich, creamy nature of the casserole without overpowering it.

FAQs

1. Can I use frozen shrimp?
Yes! Just make sure to thaw them completely and pat dry before using. Excess moisture can make the casserole watery.

2. Can I substitute the cheeses?
Absolutely. Cottage cheese can replace ricotta, or you can use provolone, fontina, or Gruyère instead of mozzarella and Parmesan for a different flavor profile.

3. Do I need to pre-cook the shrimp?
No — the shrimp cook perfectly in the oven. Overcooking them before baking can make them rubbery.

4. Can I make this dairy-free?
Yes. Use plant-based ricotta, shredded vegan mozzarella, and dairy-free Parmesan alternatives. Replace butter with olive oil and skip the breadcrumbs or use gluten-free options.

5. What’s the best way to make it extra crispy on top?
For a crispier finish, broil the casserole for the last 2 minutes of baking. Keep a close eye to avoid burning.

6. Is this recipe kid-friendly?
Definitely! Shrimp has a mild flavor that kids love, especially when paired with creamy cheese and mild spinach.

Ingredient Spotlight

Shrimp

Shrimp are the star of this dish, offering a sweet, briny flavor and tender texture.
Buying Tip: Choose medium or large shrimp that are peeled and deveined for convenience. Fresh or frozen both work well, but if frozen, thaw thoroughly before using.
Storage: Keep shrimp refrigerated and cook within 1–2 days of purchase.

Spinach

Spinach adds a vibrant green color and mild, earthy flavor that balances the richness of the cheese.
Tip: Fresh spinach wilts quickly — don’t overcook it in the skillet. You can substitute baby spinach, kale, or Swiss chard for variety.
Storage: Store fresh spinach in the refrigerator, loosely wrapped in paper towels inside a plastic bag, for up to 5 days.

Pro Cooking Tips

• Dry the shrimp well before mixing to avoid excess liquid in the casserole.
• Use freshly grated cheese for better melt and flavor — pre-shredded cheese often contains anti-caking agents that affect texture.
• Don’t overbake. Shrimp cook fast, so once the top is golden and bubbly, it’s done.
• Let it rest before slicing. This allows the cheese to set and the layers to hold their shape.
• Broil briefly at the end for a beautiful golden crust.

Storage & Freezing Guide

• Refrigerate: Store leftovers in airtight containers for up to 3 days.
• Freeze: Wrap the cooled casserole tightly in foil and plastic wrap. Freeze for up to 2 months.
• Reheat: Thaw overnight in the fridge and bake at 350°F until hot. For small portions, microwave with a splash of milk or cream to retain moisture.
• Do not refreeze previously frozen and reheated portions, as shrimp texture can degrade.
