Ingredients
Pasta Shells
Use about 12 ounces of medium pasta shells. Shells are ideal because their shape holds onto the creamy sauce.
Cook the pasta just until al dente because it will continue cooking in the oven.
Green Peas
Use about 2 cups of green peas. Fresh or frozen peas both work well.
If using frozen peas, there is no need to fully thaw them before adding them to the dish.
Butter
Butter provides richness and forms the base of the creamy sauce.
All-Purpose Flour
Flour thickens the sauce and creates a smooth, creamy consistency when combined with butter and milk.
Milk
Whole milk gives the sauce a rich texture, but 2% milk can also be used.
Cheddar Cheese
Shredded cheddar provides the classic cheesy flavor. Sharp cheddar is especially delicious, but mild cheddar works well for a gentler flavor.
Parmesan Cheese
A little grated Parmesan adds savory flavor and helps create a golden topping.
Seasonings
Keep the seasoning simple with salt, black pepper, garlic powder, and a small pinch of dried Italian seasoning if desired.
How to Make Oven-Baked Spring Pea Shell Pasta
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9-by-13-inch baking dish and set it aside.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil.
Add the pasta shells and cook according to the package directions, stopping when they are just al dente.
Reserve about half a cup of pasta water, then drain the shells.
Do not overcook the pasta because it will continue cooking while the casserole bakes.
Step 3: Prepare the Cheese Sauce
Melt the butter in a large saucepan over medium heat.
Sprinkle in the flour and whisk continuously for about 1 minute.
Gradually pour in the milk while whisking constantly to prevent lumps.
Continue cooking until the sauce thickens and becomes smooth.
Reduce the heat to low and add the shredded cheddar cheese and Parmesan.
Stir until the cheese has completely melted.
Season with salt, black pepper, and garlic powder.
If the sauce seems too thick, add a small amount of the reserved pasta water.
Step 4: Add the Peas
Stir the green peas into the warm cheese sauce.
If using frozen peas, they can be added directly from the freezer. The heat from the sauce will warm them.
Step 5: Combine With the Pasta
Add the drained pasta shells to the cheese sauce.
Gently stir until the shells are completely coated.
Be careful not to crush the shells.
Step 6: Assemble the Casserole
Transfer the cheesy pasta and peas to the prepared baking dish.
Spread everything into an even layer.
Sprinkle additional shredded cheddar and Parmesan over the top.
Step 7: Bake
Place the casserole in the preheated oven.
Bake uncovered for approximately 20 to 25 minutes, or until the cheese is melted, bubbling, and lightly golden around the edges.
For a more deeply browned topping, place the casserole under the broiler for 1 to 2 minutes at the end. Watch carefully because the cheese can burn quickly.
Step 8: Rest and Serve
Remove the casserole from the oven and let it rest for approximately 5 to 10 minutes before serving.
This allows the sauce to settle slightly and makes the pasta easier to scoop.
Tips for the Best Spring Pea Pasta Bake
Cook the Pasta Until Al Dente
Do not cook the shells until completely soft. They will continue cooking in the oven, so slightly firm pasta gives the best final texture.
Shred Your Own Cheese
Freshly shredded cheese generally melts more smoothly than pre-shredded cheese and creates a creamier sauce.
Don’t Make the Sauce Too Thick
The pasta will absorb some of the sauce during baking. The cheese sauce should be slightly looser than you want the final casserole to be.
Use Frozen Peas for Convenience
Frozen peas are an excellent choice and require very little preparation. They also retain their bright color and sweet flavor.
Let It Rest
A few minutes of resting time helps the casserole come together and prevents the sauce from being excessively runny when served.
Easy Variations
Add Chicken
Stir in 1 to 2 cups of cooked, shredded or diced chicken for a complete meal.
Add Ham
Diced cooked ham pairs wonderfully with peas and cheddar cheese.
Add Bacon
Crispy cooked bacon adds a smoky, salty flavor that works beautifully with the creamy pasta.
Add More Vegetables
Try adding:
- Broccoli
- Spinach
- Asparagus
- Diced carrots
- Mushrooms
- Sweet corn
Try Different Cheese
You can replace some or all of the cheddar with:
- Monterey Jack
- Gruyère
- Colby Jack
- Mozzarella
- Fontina
What to Serve With Spring Pea Shell Pasta
This pasta bake is filling enough to serve as a complete meal, but a few simple sides make it even better.
Serve it with:
- Green salad
- Garlic bread
- Dinner rolls
- Roasted vegetables
- Steamed broccoli
- Green beans
- Tomato salad
- Crusty French bread
A crisp salad provides a refreshing contrast to the creamy pasta.
Can I Make This Pasta Bake Ahead of Time?
Yes. Assemble the casserole, cover it tightly, and refrigerate it until you are ready to bake.
Because the pasta will absorb some of the sauce while refrigerated, you may want to add a small splash of milk before baking.
If baking directly from the refrigerator, allow additional time for the casserole to heat completely.
How to Store Leftovers
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 3 to 4 days.
Reheat individual portions in the microwave or reheat larger portions covered in the oven.
Add a splash of milk before reheating if the sauce has become thick.
Can You Freeze Spring Pea Shell Pasta?
Yes. The assembled casserole can be frozen before baking or the cooked leftovers can be frozen in an airtight freezer-safe container.
For the best texture, thaw the casserole overnight in the refrigerator before baking.
Keep in mind that creamy sauces and pasta can become slightly softer after freezing and reheating.
Frequently Asked Questions
Can I use fresh peas?
Yes. Fresh spring peas are delicious in this recipe. Add them to the cheese sauce and cook until they are tender.
Can I use frozen peas?
Absolutely. Frozen peas are convenient and work particularly well for this recipe.
Can I use another type of pasta?
Yes. Penne, rotini, rigatoni, elbow macaroni, or small shells can all be substituted.
Why is my pasta bake dry?
The pasta may have absorbed too much sauce, or the cheese sauce may have been too thick before baking. Next time, make the sauce slightly thinner and reserve some pasta water to loosen it.
Can I make it without Parmesan?
Yes. Simply replace the Parmesan with additional cheddar or another cheese of your choice.
Can I make this vegetarian?
Yes. The basic recipe is vegetarian as long as the cheese and other ingredients you use are vegetarian-friendly.
