Key Ingredients for Spinach Spaghetti
Crafting this flavorful spinach spaghetti requires a handful of fresh, simple ingredients. You’ll find a detailed list with all measurements in the printable recipe card at the very end of this post, but here’s an overview of what you’ll need to gather:
- Spaghetti Noodles: The base of our dish, providing a wonderful texture to cling to the creamy sauce.
- Butter: Essential for sautéing the aromatics and adding a rich, smooth base to our sauce.
- Minced Garlic & Shallots: These aromatic powerhouses are crucial for building the dish’s deep flavor profile.
- Fresh Raw Spinach Leaves: The star ingredient, offering both vibrant color and a boost of nutrients.
- Garlic Salt, Onion Powder, Black Pepper: A simple seasoning blend to enhance the overall taste.
- Grated Parmesan Cheese: Adds a salty, umami depth and contributes to the sauce’s creamy consistency.
- Olive Oil: Used sparingly to prevent pasta from sticking.
- Reserved Pasta Water: Your secret weapon for achieving the perfect sauce consistency.

Ingredient Notes and Helpful Substitutions
Understanding each ingredient’s role and knowing possible substitutions can help you tailor this recipe to your liking or what you have on hand:
SPINACH: For the best results, always opt for fresh, raw spinach in this recipe. While convenient, frozen spinach tends to be too watery after thawing, which can dilute the flavor and consistency of your creamy sauce. If you only have frozen, make sure to thaw it completely and squeeze out as much excess water as possible before adding it to the skillet. Regarding type, both mature spinach and baby spinach work well. Baby spinach is generally milder and slightly sweeter, while mature spinach offers a deeper, earthier flavor. Since we’ll be blending the spinach into the sauce, the size isn’t critical, so choose based on your flavor preference.
PASTA: This recipe is designed for already cooked pasta, so ensure you factor in the cooking time for your spaghetti. To prevent the cooked spaghetti from clumping together while you prepare the sauce, you have a couple of options: after draining, you can quickly rinse it with cool water to halt the cooking process and then place it in a bowl of room-temperature water until needed. Alternatively, tossing the drained pasta with a small amount of olive oil (about a teaspoon) works equally well. While spaghetti is traditional for this dish, other long pasta shapes like linguine or fettuccine, or even short pasta like penne or fusilli, would also pair wonderfully with this rich sauce.
BUTTER & GARLIC: These form the aromatic foundation of our sauce. Salted or unsalted butter can be used; if using salted, you might adjust the added garlic salt slightly. Freshly minced garlic is always recommended for the best flavor, but pre-minced garlic from a jar can be a convenient substitute in a pinch.
SHALLOTS: Shallots provide a milder, sweeter onion flavor than regular onions, complementing the garlic beautifully. If you don’t have shallots, a small amount of finely minced yellow onion or even a red onion (for a slightly sharper bite) can be used as an alternative.
PARMESAN CHEESE: Freshly grated Parmesan cheese will always yield the best flavor and melt most smoothly into the sauce. Pre-grated Parmesan can sometimes contain anti-caking agents that affect its texture when melted. You can also experiment with other hard, salty cheeses like Pecorino Romano for a bolder flavor, or a blend of Italian cheeses.
How to Make Delicious Spinach Spaghetti
These step-by-step photos and detailed instructions are here to guide you visually through the recipe. For a quick jump to the printable version, complete with precise measurements and instructions, you can Jump to Recipe at the bottom of this post.
- Cook the Spaghetti: Begin by cooking your spaghetti noodles according to package directions until they are al dente. This ensures the pasta retains a slight bite and doesn’t become mushy when tossed with the sauce. Before draining, reserve about 1/2 cup of the starchy pasta water – this will be essential for adjusting the sauce consistency later. Drain the remaining water thoroughly. To prevent the noodles from sticking together while you prepare the sauce, toss them with a teaspoon of olive oil and set aside.
- Sauté Aromatics: In a large, deep-sided skillet, melt the butter over medium-high heat. Once melted, add the minced garlic and shallots. Sauté these aromatics for 1-2 minutes, stirring frequently, until they become fragrant and slightly softened. Be careful not to burn the garlic.
- Wilt the Spinach: Add the fresh spinach to the skillet, a couple of handfuls at a time. Stir continuously with a rubber spatula as the spinach begins to wilt down. Continue adding spinach until all of it has been incorporated and has significantly reduced in volume.

Stir all the ingredients together well, ensuring the seasonings are evenly distributed. Continue cooking for another minute or two until the spinach is completely wilted and tender, absorbing all the flavors.

Add the grated Parmesan cheese to the mixture. Blend until the sauce is mostly smooth with no large chunks of spinach remaining. You may need to stop halfway through and scrape down the sides of the chopper or blender to ensure everything is evenly processed.

Add the pureed spinach mixture to the pasta. Heat gently over low heat, tossing continuously, just until the pasta and sauce are warmed through and evenly combined. If the sauce seems too thick, gradually add small amounts of the reserved pasta water, a tablespoon at a time, until you achieve your desired creamy consistency. Serve immediately and enjoy!

Frequently Asked Questions & Expert Tips for Success
To help you perfect your spinach spaghetti and answer common queries, here are some frequently asked questions and invaluable expert tips:
Absolutely, you can use baby spinach. Since the recipe involves blitzing the spinach into a sauce, the initial size isn’t a critical factor. However, it’s worth noting that baby spinach typically has a milder, slightly sweeter flavor profile compared to mature spinach, which tends to have a deeper, earthier taste. Both varieties will yield delicious results in this dish, so feel free to choose whichever you prefer or have readily available. The subtle difference in flavor won’t detract from the overall enjoyment.
Any cooled leftovers should be transferred to an airtight container and stored in the refrigerator. It will keep fresh for up to 4 days. When reheating, you can use a microwave or gently warm it on the stovetop. If the pasta seems a bit dry or the sauce too thick, add a small dash of water or a splash of milk/broth to help moisten it and restore its creamy texture. Stir well while reheating.
Yes, this recipe is incredibly versatile and pairs wonderfully with added protein. Cooked chicken (shredded or diced), sautéed shrimp, Italian sausage, or even crispy bacon bits would all be excellent additions. Simply stir your cooked protein into the pasta at the very end, along with the spinach sauce, and heat through. For a plant-based protein boost, consider adding chickpeas, white beans, or pan-fried tofu cubes.
If shallots aren’t available, you can substitute them with finely minced yellow onion. Use about half the amount of onion as you would shallots, as onions tend to have a stronger, sharper flavor. Alternatively, a pinch of onion powder can be used if you need a quick flavor boost without the texture of fresh onion.
Absolutely! For a delightful kick, add a pinch or two of red pepper flakes along with the garlic salt and onion powder. You can also garnish individual servings with extra red pepper flakes for those who enjoy more heat.
The reserved pasta water is your best friend here! If the sauce is too thick, gradually add small amounts of the reserved starchy pasta water (a tablespoon at a time) while tossing until it reaches your desired creamy consistency. The starch in the water helps bind the sauce to the pasta. If your sauce accidentally turns out too thin (which is less common with this blending method), you can try simmering it gently for a few more minutes to allow some of the liquid to evaporate, or you can add a tiny bit more grated Parmesan cheese which can help thicken it.

Serving Suggestions for Spinach Spaghetti
This creamy garlic Parmesan spinach spaghetti is a hearty and satisfying meal on its own, but it truly shines when paired with a few simple accompaniments. Serve it alongside some crusty hunks of artisan bread or warm, buttery garlic bread to soak up every last drop of that incredible sauce. A light side salad with a tangy vinaigrette would also offer a refreshing contrast to the richness of the pasta.
For an extra burst of flavor and a touch of elegance, I personally love to garnish each serving with a few shakes of red pepper flakes for a subtle warmth and a generous sprinkle of extra shredded Parmesan cheese. A fresh sprig of basil or a drizzle of high-quality olive oil can also elevate the presentation and taste. Consider pairing it with a crisp white wine like Pinot Grigio or Sauvignon Blanc for a truly delightful dining experience. Enjoy this vibrant dish as a comforting weeknight dinner or a simple yet impressive meal for guests!

Nutrition
The recipes on this blog are tested with a conventional gas oven and gas stovetop. It’s important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
