Ingredients
Scale
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
- 3 cups fresh spinach or baby spinach
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
- ¼ cup grated Parmesan cheese
Instructions
- Saute Onion and Mushrooms: Heat the olive oil in a large pot over medium heat. Add the chopped onion and sliced mushrooms, sautéing until they become tender and lightly browned, about 5-7 minutes.
- Add Seasonings: Stir in the minced garlic, salt, black pepper, and red pepper flakes (if using). Cook for about 1 minute until the garlic is fragrant but not browned.
- Add Liquid Ingredients: Pour in the low-sodium vegetable broth and fire-roasted diced tomatoes with their juices. Bring the mixture to a boil, ensuring all ingredients are combined.
- Cook Noodles: Add the thin spaghetti noodles to the boiling mixture. Cover the pot and let the noodles cook until al dente and wilted, approximately 8-10 minutes, stirring occasionally to prevent sticking.
- Add Spinach: Once the noodles are nearly cooked, stir in the fresh spinach. Cook just until the spinach wilts, which should take about 2 minutes.
- Finish and Serve: Remove the pot from heat. Stir in the grated Parmesan cheese thoroughly. Taste and adjust seasonings if needed. Serve immediately topped with extra Parmesan and fresh herbs if desired.
Notes
- Use thin spaghetti for faster cooking and even absorption of flavors.
- To keep it vegan, omit the Parmesan cheese or use a plant-based alternative.
- For extra protein, add cooked beans or tofu before serving.
- Red pepper flakes are optional but add a subtle heat.
- Stir frequently once pasta is added to prevent noodles from sticking to the bottom.
