What You’ll Need
For the Spaghetti Squash:
- 1 medium spaghetti squash (about 3-4 pounds)
- 1 tablespoon olive oil
- Salt and pepper, to taste
For the Sauce:
- 1 (14 oz) can of diced tomatoes
- 1 bell pepper, diced (any color)
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 teaspoon red pepper flakes (optional for heat)
- Fresh basil for garnish (optional)
When selecting your spaghetti squash, look for one that feels heavy for its size and has a firm skin free of soft spots. These characteristics assure optimal freshness and flavor.
How to Make Vegan Crockpot Spaghetti Squash
Step 1: Prepare the Squash
Cut the spaghetti squash in half lengthwise and remove the seeds. Drizzle olive oil over the cut sides, and season with salt and pepper.
Step 2: Set Up the Crockpot
Place the squash halves cut-side up in your crockpot. If they don’t fit quite right, you may need to place them on their side, allowing them to sit snugly.
Step 3: Assemble the Sauce
In a mixing bowl, combine the diced tomatoes, bell pepper, onion, minced garlic, oregano, basil, and red pepper flakes. Stir well to combine all the ingredients.
Step 4: Add the Sauce
Pour the tomato mixture evenly over the squash in the crockpot, ensuring that it covers the squash well. This will infuse the squash with flavor as it cooks.
Step 5: Slow Cook
Cover the crockpot and cook on low for about 6-7 hours or until the squash is tender and can be easily shredded with a fork. The sauce will thicken and meld beautifully throughout the cooking process.
Step 6: Serve
Once done, use a fork to scrape the insides of the squash, creating those spaghetti-like strands. Serve topped with the warm sauce and garnish with fresh basil if desired.
Expert Tips & Ideas
- Ensure your squash is fresh for the best flavor. Storing them in a cool, dark place will help maintain their quality.
- For added protein, consider incorporating cooked lentils or chickpeas to the sauce.
- If you want to reduce cooking time, you can microwave the squash halves for about 5 minutes before placing them in the crockpot.
- Leftovers can be stored in an airtight container in the fridge for up to 5 days. Reheat on the stovetop or microwave until warmed through.
How to Serve
This Vegan Crockpot Spaghetti Squash can be enjoyed as a standalone dish or paired with a simple green salad for added crunch and freshness. For a heartier meal, serve alongside garlic bread or roasted vegetables for a comforting touch. Consider a glass of chilled white wine or a sparkling water infused with lemon to elevate the dining experience.
Presentation matters, so remember to serve it in the pumpkin shells for an eye-catching table display. This not only adds a rustic charm but also keeps the dish warm for longer.
Common Questions
