Ingredients

Here is everything you need for creamy spinach and mushroom spaghetti:

For the Pasta:

· 12 ounces spaghetti (or linguine, fettuccine)
· Salt for the pasta water

For the Sauce:

· 2 tablespoons unsalted butter
· 2 tablespoons olive oil
· 8 ounces cremini or button mushrooms, sliced
· 4 cloves garlic, minced
· 1 cup heavy cream (or half-and-half)
· ½ cup low-sodium chicken or vegetable broth
· 1 cup freshly grated Parmesan cheese (divided)
· ½ teaspoon salt
· ¼ teaspoon black pepper
· ¼ teaspoon ground nutmeg (optional)
· 4 cups fresh spinach (about 4 ounces)

For Garnish (Optional):

· Fresh parsley, chopped
· Red pepper flakes

Step-by-Step Instructions

Step 1: Cook the Spaghetti

Bring a large pot of generously salted water to a boil. Add the spaghetti and cook according to package directions until al dente. Reserve 1 cup of pasta water before draining. Drain the spaghetti and set aside.

Step 2: Sauté the Mushrooms

While the pasta cooks, heat a large skillet or Dutch oven over medium-high heat. Add the butter and olive oil. Once the butter is melted and bubbling, add the sliced mushrooms. Cook for 4 to 5 minutes, stirring occasionally, until the mushrooms are golden brown and have released their liquid.

Step 3: Add the Garlic

Add the minced garlic to the skillet and cook for 30 to 60 seconds until fragrant, stirring constantly.

Step 4: Make the Cream Sauce

Reduce the heat to medium-low. Pour in the heavy cream and chicken broth. Whisk to combine, scraping up any browned bits from the bottom of the pan. Bring to a gentle simmer. Stir in ½ cup of the Parmesan cheese, salt, pepper, and nutmeg (if using). Cook for 2 to 3 minutes until the sauce thickens slightly.

Step 5: Wilt the Spinach

Add the fresh spinach to the skillet in batches, stirring gently until wilted, about 1 to 2 minutes.

Step 6: Combine Pasta and Sauce

Add the cooked spaghetti to the skillet. Toss to coat the pasta evenly in the creamy sauce. If the sauce seems too thick, add reserved pasta water a little at a time until it reaches your desired consistency.

Step 7: Serve

Transfer the creamy spinach and mushroom spaghetti to serving bowls. Sprinkle with the remaining ½ cup of Parmesan cheese. Garnish with fresh parsley and red pepper flakes if desired. Serve immediately.

Cooking Tips and Pro Tips for Best Results

· Do not overcrowd the mushrooms: Cook them in a single layer so they brown, not steam. If your skillet is small, cook the mushrooms in two batches.
· Use freshly grated Parmesan: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Grate Parmesan from a block for the best, creamiest sauce.
· Reserve pasta water: The starchy pasta water helps thin the sauce and helps it cling to the spaghetti.
· Do not overcook the spinach: Spinach wilts quickly. Add it at the end and stir just until wilted to preserve its bright green color and fresh flavor.
· Make it spicy: Add ½ teaspoon of red pepper flakes with the garlic.
· Add protein: Top with grilled chicken, crispy bacon, or sautéed shrimp for a heartier meal.

Variations and Substitutions

· Chicken spinach mushroom pasta: Add 1 cup of diced cooked chicken to the skillet with the spinach.
· Bacon spinach mushroom pasta: Add ½ cup of crumbled cooked bacon at the end.
· Sun-dried tomato pasta: Add ¼ cup of chopped sun-dried tomatoes along with the spinach.
· Lighter version: Use half-and-half instead of heavy cream. The sauce will be thinner.
· Dairy-free: Use full-fat coconut milk and dairy-free Parmesan.
· Gluten-free: Use gluten-free spaghetti.
· Add lemon: Add 1 tablespoon of lemon juice and 1 teaspoon of lemon zest at the end for brightness.

Serving Suggestions

This creamy spinach and mushroom spaghetti is delicious served:

· As a main course: With a simple green salad and crusty bread.
· As a side dish: Alongside grilled chicken, steak, or fish.
· For a vegetarian dinner: Complete and satisfying on its own.
· For a date night: Elegant enough for company.

Frequently Asked Questions
