Full Recipe:

Ingredients

  • 2 teaspoons extra-virgin olive oil
  • ½ medium yellow onion, chopped
  • 1 (8 oz.) package button mushrooms, sliced
  • 2 cloves garlic, minced
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon red pepper flakes (optional)
  • 2 cups low-sodium vegetable broth
  • 1 (14.5 oz.) can fire-roasted diced tomatoes
  • 10 oz. thin spaghetti (whole wheat preferred)
  • 3 cups fresh spinach or baby spinach
  • ¼ cup grated Parmesan cheese, plus extra for serving

For serving:

  • ¼ cup fresh chopped basil or parsley (optional)

Directions

  1. Heat olive oil in a medium pot over medium heat. Add onion and mushrooms and sauté for 5-7 minutes, until tender and most of the mushroom liquid evaporates.
  2. Add garlic, salt, black pepper, and red pepper flakes (if using). Sauté for another 30 seconds.
  3. Increase heat to high and add diced tomatoes and vegetable broth. Bring to a boil.
  4. Add spaghetti and stir until the noodles begin to wilt and fit into the pot. Cover, reduce heat to medium-low, and cook for 5 minutes, ensuring the liquid remains at a low boil.
  5. Remove the lid and add spinach in batches, stirring until wilted.
  6. Remove from heat, cover, and let sit for a few minutes.
  7. Stir in Parmesan cheese, adjust seasoning, and serve with fresh basil or parsley and extra Parmesan, if desired.

What Makes One-Pot Pasta So Special?

One-pot meals have become increasingly popular due to their convenience and minimal cleanup. Instead of boiling pasta separately and preparing a sauce in another pan, this recipe simplifies the process by cooking everything in a single pot. This method allows the spaghetti to absorb the vegetable broth and tomato juices, infusing every bite with rich, deep flavors. The result is a dish that tastes like it has been simmering for hours, even though it comes together in less than half an hour.

The Perfect Balance of Ingredients

This One-Pot Vegetarian Spaghetti is a well-balanced dish with a combination of vegetables, seasonings, and a touch of Parmesan cheese to create a creamy finish. Each ingredient plays a key role in making this dish both delicious and satisfying:

  • Mushrooms: Their earthy, umami flavor enhances the depth of the dish while providing a meaty texture.
  • Spinach: This leafy green adds a boost of nutrients and freshness, complementing the richness of the tomatoes.
  • Fire-Roasted Tomatoes: Unlike regular diced tomatoes, fire-roasted ones have a smoky depth of flavor that adds complexity to the sauce.
  • Vegetable Broth: Cooking the pasta directly in the broth not only saves time but also infuses the noodles with extra flavor.
  • Parmesan Cheese: A small amount of Parmesan adds a creamy and slightly salty touch, tying all the flavors together.

Tips for the Best One-Pot Pasta

To ensure your One-Pot Vegetarian Spaghetti turns out perfect every time, keep these tips in mind:

  • Use Thin Spaghetti or Angel Hair Pasta: These types of pasta cook quickly and absorb the broth efficiently without becoming mushy.
  • Stir Occasionally: To prevent the pasta from sticking together, stir it every few minutes as it cooks.
  • Adjust the Liquid as Needed: If the pasta absorbs too much broth before it finishes cooking, add a little extra broth or water to maintain a saucy consistency.
  • Season to Taste: Since broths and Parmesan cheese contain salt, taste the dish before adding extra seasoning.
  • Let It Rest Before Serving: After cooking, let the spaghetti sit covered for a few minutes to allow the flavors to meld together.

Delicious Variations to Try

One of the best things about One-Pot Vegetarian Spaghetti is how adaptable it is. Here are some ways to change up the recipe to suit your tastes:

  • Make It Vegan: Skip the Parmesan cheese or replace it with a dairy-free alternative to make this dish completely plant-based.
  • Add More Vegetables: Bell peppers, zucchini, carrots, or even artichokes can add extra color, texture, and nutrition.
  • Incorporate Protein: If you want a protein boost, add chickpeas, white beans, or even tofu crumbles.
  • Spice It Up: For extra heat, increase the red pepper flakes or add a dash of hot sauce.
  • Swap the Pasta: If you prefer a different type of noodle, whole wheat pasta, gluten-free pasta, or even lentil pasta can work well.

Pairing Suggestions

Although this dish is satisfying on its own, pairing it with a simple side can make the meal even more complete. Here are a few great options:

  • Garlic Bread: A slice of warm, crispy garlic bread is perfect for scooping up the flavorful sauce.
  • Side Salad: A fresh green salad with balsamic vinaigrette balances the richness of the pasta.
  • Roasted Vegetables: Try roasted broccoli, asparagus, or Brussels sprouts for a nutritious side.
  • Glass of Wine: If you enjoy wine with dinner, a light Pinot Noir or a crisp Sauvignon Blanc pairs nicely with this dish.

Why One-Pot Vegetarian Spaghetti is Great for Meal Prep

This recipe isn’t just quick and easy—it’s also fantastic for meal prep. Since the flavors deepen over time, leftovers taste even better the next day. Here’s how to store and reheat it:

  • Freeze: This dish can be frozen for up to 3 months. Allow it to cool completely before transferring to a freezer-safe container.
  • Reheat: Warm it up in a pan over low heat, adding a splash of broth or water to bring back the creamy consistency.
