Cheesy Spinach Pasta Sauce

A creamy, vibrant cheesy spinach pasta sauce is a quick way to turn plain pasta into a comforting, nutrient-packed meal. It’s perfect for weeknight dinners, and with a few swaps it can be adjusted for toddlers, picky eaters, or adults who want a richer version.

Why this sauce works

This sauce balances bright greens with smooth, melty cheese and a touch of aromatics. Spinach wilts down and blends into the sauce, which keeps the texture kid-friendly while adding iron and vitamins. Parmesan (or a blend of cheeses) brings umami without overwhelming the spinach, and a splash of milk or cream smooths everything out.

Ingredients (serves 4)

• 10–12 oz (300–350 g) fresh spinach, washed, or 10 oz frozen spinach (thawed and drained)
• 1 cup milk or 1/2 cup cream + 1/2 cup milk (adjust for desired richness)
• 1–1 1/2 cups shredded cheese (Parmesan, mozzarella, cheddar, or a mix)
• 2 tbsp butter or olive oil
• 1 small onion, finely chopped (optional)
• 1–2 cloves garlic, minced (optional)
• 1 tbsp flour (for thickening) or 1/4 cup cream cheese for a gluten-free thicken
• Salt and black pepper to taste
• Pinch of nutmeg (optional, pairs well with spinach)
• Cooked pasta of choice

Method

1. Sauté aromatics: In a large skillet, melt butter (or heat oil) over medium heat. Add chopped onion and cook until translucent, then add garlic and cook 30 seconds to 1 minute.
2. Add spinach: Stir in fresh spinach a handful at a time until wilted, or add drained frozen spinach and heat through. If using fresh, you can roughly chop it once wilted for a finer texture.
3. Make the base: Sprinkle the flour over the spinach mixture and stir for a minute to cook the raw flour taste. Slowly whisk in milk (or cream), smoothing any lumps. Bring to a gentle simmer until the sauce thickens slightly.
4. Add cheese and finish: Reduce heat to low, stir in shredded cheese until melted and the sauce is smooth. Season with salt, pepper, and a pinch of nutmeg. If the sauce is too thick, loosen with reserved pasta water. If too thin, simmer briefly to reduce.
5. Combine with pasta: Toss cooked pasta directly into the skillet so the sauce clings to the noodles. Serve immediately with extra grated cheese.

Variations and tips

• Creamy toddler version: Use a milder cheese like mild cheddar or mozzarella and skip added salt; blend the finished sauce for a very smooth texture tailored to babies and toddlers. More tips for preparing pasta for little ones are available in the baby pasta resource.
• Add-ins: Stir in cooked chicken, bacon bits, sun-dried tomatoes, or sautéed mushrooms for more substance.
• Dark leafy swap: Kale or Swiss chard can replace spinach — cook longer until tender and consider blending for smoothness.
• Make-ahead: Store sauce separately for up to 3 days; reheat gently with a splash of milk to revive creaminess.
• Dairy-free option: Use a cashew cream base (blend soaked cashews with water) and nutritional yeast for cheesiness.

Serving suggestions

Serve this sauce with short pasta shapes like penne, fusilli, or shells that trap the sauce. A simple green salad and crusty bread complete the meal. For a lighter option, pair with whole-grain pasta and a squeeze of lemon to brighten the spinach flavors.
