Ingredients
Vegetables and Aromatics
- 2 teaspoons extra-virgin olive oil
- ½ medium yellow onion, chopped
- 1 (8 oz.) package button mushrooms, sliced
- 2 cloves garlic, minced
Seasonings
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon red pepper flakes (optional)
Liquids and Pasta
- 2 cups low-sodium vegetable broth
- 1 (14.5 oz.) can fire-roasted diced tomatoes
- 10 oz. thin spaghetti noodles
Finishing Touches
- 3 cups fresh spinach or baby spinach
- ¼ cup grated Parmesan cheese
Instructions
- Saute Onion and Mushrooms: Heat 2 teaspoons of extra-virgin olive oil in a large pot over medium heat. Add the chopped yellow onion and sliced button mushrooms, sautéing until they are tender and fragrant, about 5 minutes.
- Add Seasonings: Stir in minced garlic, ½ teaspoon salt, ¼ teaspoon black pepper, and ¼ teaspoon red pepper flakes if using. Sauté the mixture briefly for about 1 minute until the garlic is aromatic.
- Add Liquid Ingredients: Pour in 2 cups of low-sodium vegetable broth and the entire can of fire-roasted diced tomatoes. Bring the mixture to a boil.
- Cook Noodles: Add the 10 ounces of thin spaghetti noodles to the boiling liquid. Cover the pot with a lid and cook according to the spaghetti’s package instructions, typically around 8-10 minutes, stirring occasionally, until the noodles are tender and have absorbed most of the liquid.
- Add Spinach: Stir in 3 cups of fresh spinach into the pot. Continue to cook with the lid off, stirring occasionally, until the spinach wilts, about 2 minutes.
- Finish and Serve: Remove the pot from heat. Stir in ¼ cup of grated Parmesan cheese until melted and well combined. Taste and adjust the seasoning with extra salt, pepper, or herbs as desired. Serve hot, optionally garnished with additional Parmesan or fresh herbs.
Notes
- You can substitute the thin spaghetti with any pasta shape of your choice, adjusting cooking time accordingly.
- For a vegan version, omit the Parmesan cheese or replace it with a plant-based alternative.
- Use fire-roasted tomatoes for added depth of flavor; regular diced tomatoes work as well but will yield a milder taste.
- Adding red pepper flakes is optional but adds a pleasant heat to the dish.
- This recipe is gluten-free adaptable by using gluten-free pasta.
