Ingredients
Scale
Vegetables & Aromatics
- 2 teaspoons extra-virgin olive oil
- ½ medium yellow onion, chopped
- 1 (8 oz.) package button mushrooms, sliced
- 2 cloves garlic, minced
- 3 cups fresh spinach or baby spinach
Seasonings & Spices
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon red pepper flakes, optional
Liquids & Canned Ingredients
- 2 cups low-sodium vegetable broth
- 1 (14.5 oz.) can fire-roasted diced tomatoes
Pasta & Cheese
- 10 oz. thin spaghetti noodles
- ¼ cup grated Parmesan cheese
Instructions
- Saute Onion and Mushrooms: Heat the extra-virgin olive oil in a large pot over medium heat. Add the chopped onion and sliced mushrooms and sauté until they become tender and fragrant, about 5-7 minutes.
- Add Seasonings: Stir in the minced garlic, salt, black pepper, and red pepper flakes if using. Cook briefly for about 1 minute to release their aromas.
- Add Liquid Ingredients: Pour in the low-sodium vegetable broth and fire-roasted diced tomatoes with their juices. Bring the mixture to a boil over medium-high heat.
- Cook Noodles: Add the thin spaghetti noodles to the boiling broth and tomatoes. Cover the pot and simmer, stirring occasionally, until the noodles are tender and cooked through, about 8-10 minutes.
- Add Spinach: Stir in the fresh spinach and cook until wilted, about 2 minutes, ensuring it is evenly distributed throughout the pasta.
- Finish and Serve: Remove the pot from heat and stir in the grated Parmesan cheese. Taste and adjust seasonings if needed. Serve immediately, optionally garnished with fresh herbs and extra Parmesan cheese.
Notes
- For a vegan version, omit the Parmesan cheese or substitute with a plant-based cheese alternative.
- Use gluten-free spaghetti noodles if you require a gluten-free diet.
- You can add other vegetables like bell peppers or zucchini for extra nutrition and flavor.
- Red pepper flakes are optional but add a nice subtle heat; adjust to your spice preference.
- Stir the pasta occasionally when cooking to prevent sticking to the bottom of the pot.
