Why This Recipe Works

The key to a great creamy spinach pasta bake is in the layering of flavors and textures. By cooking the pasta al dente and then finishing it in the creamy sauce, you create a dish that's both comforting and satisfying. The spinach adds a burst of freshness, while the garlic and onion provide a depth of flavor.

Another important aspect of this recipe is the use of high-quality ingredients.

And don't forget to season as you go, as this will help bring out the flavors of each component.

Ingredients You’ll Need

When it comes to making a creamy spinach pasta bake, the ingredients are just as important as the technique. You'll need a few essential items, including pasta, cheese, spinach, and garlic. Be sure to choose high-quality ingredients, as this will make a big difference in the final dish.

Here are a few shopping tips to keep in mind: look for fresh spinach with no wilting or brown edges, and choose a good-quality pasta that will hold up well to the creamy sauce. You'll also want to select a variety of cheese that melts well, such as mozzarella or parmesan.

1 lb (450g) pasta of your choiceI like to use a short, tubular pasta shape like penne or rigatoni, as it holds the creamy sauce well. Look for a high-quality pasta that is made with durum wheat semolina and has a rough texture to help the sauce cling to it.
2 tbsp (30g) olive oilUse a good-quality olive oil with a mild flavor, as it will add depth to the dish without overpowering the other ingredients. You can also use other neutral-tasting oils like canola or grapeseed if you prefer.
1 onion, finely choppedI like to use a sweet onion like Vidalia or Maui, as it adds a depth of flavor to the dish without being too overpowering. Be sure to chop the onion finely, as this will help it cook evenly and quickly.
3 cloves garlic, mincedGarlic is a key ingredient in this recipe, as it adds a pungent flavor that complements the spinach and cheese. Use fresh garlic for the best flavor, and be sure to mince it finely so it distributes evenly throughout the dish.
1 package frozen spinach, thawed and drainedI like to use frozen spinach because it's convenient and has a milder flavor than fresh spinach. Be sure to squeeze out as much water as possible from the thawed spinach, as this will help the sauce cling to the pasta better.
1 cup (250g) grated mozzarella cheeseMozzarella is a great melting cheese that adds creaminess to the dish. Look for a high-quality mozzarella that is made from whole milk and has a smooth, even texture.
1/2 cup (120g) grated parmesan cheeseParmesan is a sharp, salty cheese that adds depth to the dish. Use a high-quality parmesan that is aged for at least 12 months, as this will give it a richer, more complex flavor.
1 tsp (5g) dried basilBasil is a classic Italian herb that pairs well with spinach and cheese. Use dried basil if you don't have fresh basil on hand, as it will still add a nice flavor to the dish.
1 tsp (5g) saltSalt is essential for bringing out the flavors in the dish. Use a flaky sea salt or kosher salt for the best flavor, and be sure to taste the dish as you go to ensure it's seasoned properly.
1/2 tsp (2g) black pepperBlack pepper adds a nice depth of flavor to the dish. Use freshly ground black pepper for the best flavor, and be sure to taste the dish as you go to ensure it's seasoned properly.
2 tbsp (30g) unsalted butterButter adds a richness and creaminess to the sauce. Use high-quality, unsalted butter for the best flavor, and be sure to melt it slowly over low heat to prevent it from burning.
1 cup (250ml) heavy creamHeavy cream is essential for creating a creamy sauce. Look for a high-quality heavy cream that is made from whole milk and has a rich, velvety texture.

How to Make Creamy Spinach Pasta Bake

1
Bring a large pot of salted water to a boil and cook the pasta according to the package instructions until it's al dente. Reserve 1 cup of pasta water before draining the spaghetti.
2
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook until it's translucent and starting to caramelize, about 5-7 minutes.
3
Add the minced garlic to the skillet and cook for an additional 1-2 minutes, until fragrant. Be careful not to burn the garlic.
4
Add the thawed spinach to the skillet, along with the dried basil, salt, and black pepper. Cook until the spinach has wilted and the mixture is heated through, about 2-3 minutes.
5
In a large saucepan, melt the butter over low heat. Add the heavy cream and bring the mixture to a simmer. Let it cook for 2-3 minutes, until it's slightly reduced and creamy.
6
Add the grated mozzarella and parmesan cheese to the saucepan, stirring until the cheese is melted and the sauce is smooth. Season with salt and pepper to taste.
7
Add the cooked pasta to the cheese sauce, tossing to combine. If the sauce seems too thick, add a bit of the reserved pasta water to thin it out.
8
Transfer the pasta mixture to a baking dish and top with additional grated cheese if desired. Bake in a preheated oven at 375°F (190°C) for 15-20 minutes, until the top is golden brown and the sauce is bubbly.
9
Remove the pasta bake from the oven and let it rest for 5-10 minutes before serving. This will help the sauce set and the flavors to meld together.
10
Serve the creamy spinach pasta bake hot, garnished with additional basil or parmesan cheese if desired. Enjoy!
11
To make ahead, prepare the pasta bake up to the point of baking, then refrigerate or freeze until ready to bake. Let it come to room temperature before baking, and add a few extra minutes to the cooking time if necessary.
