Step-by-Step Instructions for One Pot Recipe with Spaghetti Squash
Step 1: Prepare the Spaghetti Squash
Pierce the squash several times with a fork. Microwave for 5 minutes to soften the skin. Cut in half lengthwise and scoop out the seeds. Brush the inside with 1 tablespoon of olive oil and season with salt and pepper.
Pro tip: Save the seeds! They can be roasted like pumpkin seeds for a nutritious snack.
Step 2: Roast the Squash
Place the squash halves cut-side down in your large pot or Dutch oven. Add ½ cup water to the pot. Cover and cook over medium heat for 15-20 minutes, until the squash is tender enough to scrape into strands.
Insight: Steam-roasting the squash in the same pot you’ll use for the entire dish infuses it with flavor while saving you from washing multiple pans.
Step 3: Prepare the Base
Remove the squash halves and set aside to cool. In the same pot, heat the remaining olive oil over medium heat. Add the onion and sauté for 3-4 minutes until translucent. Add the garlic and cook for another 30 seconds until fragrant.
Step 4: Build the Flavor
Add the bell pepper and zucchini to the pot. Sauté for 5 minutes until they begin to soften. Add the cherry tomatoes, canned tomatoes, vegetable broth, dried herbs, and red pepper flakes. Bring to a simmer.
Step 5: Combine and Finish
Using a fork, scrape the squash flesh into spaghetti-like strands. Add the strands to the simmering pot, stirring gently to combine. Cook for an additional 5-10 minutes until all flavors are well incorporated and the liquid has reduced slightly. Stir in fresh basil and adjust seasoning to taste.
