Ingredients Breakdown
- 1 medium spaghetti squash (about 2.5–3 lbs)
- 1 lb Italian sausage (hot or mild; casings removed)
- 1 tablespoon olive oil (as needed)
- 1 yellow onion, diced
- 3 garlic cloves, minced
- 2 carrots, diced
- 2 celery stalks, diced
- 1 teaspoon dried oregano
- 1/2 teaspoon red pepper flakes (optional, for heat)
- 6 cups chicken broth (low sodium recommended)
- 1 (14.5 oz) can crushed or diced tomatoes
- 1 bay leaf
- 1–2 tablespoons lemon juice or red wine vinegar (to finish)
- 2 cups chopped kale or baby spinach
- Salt and black pepper, to taste
- Grated Parmesan, for serving (optional but elite)
- Fresh parsley or basil, chopped, for garnish
How to Make It – Instructions
- Roast the squash: Heat oven to 400°F (205°C). Halve the squash lengthwise, scoop seeds, rub cut sides with a bit of oil, and season with salt and pepper. Place cut-side down on a lined sheet and roast 35–45 minutes until a fork slides in easily.
Cool slightly, then scrape into strands.
- Brown the sausage: In a large pot, cook sausage over medium-high heat, breaking it up until browned and crisp in spots, 6–8 minutes. If the pot looks dry, add a touch of olive oil. Drain excess fat if needed, but leave a tablespoon for flavor.
- Sweat the aromatics: Add onion, carrot, and celery.
Cook 5–6 minutes until softened. Stir in garlic, oregano, and red pepper flakes; cook 30–60 seconds until fragrant.
- Build the broth: Stir in chicken broth, tomatoes, and bay leaf. Bring to a gentle boil, then simmer 10–12 minutes to marry flavors.
- Add greens and squash: Stir in kale or spinach and the spaghetti squash strands.
Simmer 3–5 more minutes. Remove bay leaf.
- Finish and balance: Add lemon juice or vinegar. Taste and season with salt and pepper.
You want bright, savory, and a little sweet from the squash.
- Serve: Ladle into bowls and top with Parmesan and herbs. Snap a pic. Pretend you have a nonna.
Preservation Guide
- Fridge: Store in airtight containers up to 4 days.
The flavors deepen overnight—chef’s kiss.
- Freezer: Freeze up to 3 months. Cool completely, portion, and leave headspace. Thaw in the fridge, then reheat gently.
- Reheating: Warm on the stove over medium-low.
If it thickens, add a splash of broth or water to loosen.
Nutritional Perks
- Lower-carb comfort: Spaghetti squash sneaks in fiber with far fewer carbs than pasta.
- Protein-powered: Sausage adds staying power, making this a satisfying main.
- Micros that matter: Carrots, greens, and tomatoes deliver vitamin A, C, potassium, and antioxidants.
- Customizable fat profile: Use chicken sausage or turkey sausage for a leaner bowl, or go full flavor if that’s your vibe.
Pitfalls to Watch Out For
- Overcooking the squash: If you roast it to mush, you’ll lose the noodle-like strands. Aim for tender, not collapsed.
- Skimping on acid: Without a pop of lemon or vinegar, the soup can taste flat. Finish strong.
- Grease overload: Some sausages are super fatty.
Drain excess so the broth stays clean and craveable.
- Salt creep: Broth, sausage, and Parmesan all carry salt. Taste before salting—your future self will thank you.
Mix It Up
- Creamy twist: Stir in 1/3 cup heavy cream or coconut milk at the end for a silky finish.
- Tuscan vibes: Add white beans and swap kale for spinach. Extra Parmesan on top, obviously.
- Smoky flair: Use smoked sausage or add a pinch of smoked paprika.
- Veggie boost: Mushrooms, zucchini, or roasted red peppers play well here.
- Heat level: Go mild sausage for kids; add Calabrian chili paste for the spice squad.
FYI: a little goes far.
FAQ
Can I make this soup dairy-free?
Yes. Skip the Parmesan and finish with olive oil and fresh herbs. If you want creaminess, use unsweetened coconut milk or a splash of cashew cream.
What’s the fastest way to cook the spaghetti squash?
Microwave it.
Pierce all over with a fork, microwave 5–7 minutes until it softens enough to cut, then halve and microwave cut-side down 6–10 more minutes. Not as roasty, but very weekday-friendly.
Can I use pre-cooked sausage?
Absolutely. Slice or crumble and brown lightly for flavor before adding the veggies.
It won’t render as much fat, so add a teaspoon of oil if the pot looks dry.
How do I keep the greens vibrant?
Add them near the end and don’t over-simmer. Spinach needs 1–2 minutes; kale needs 3–5. Bright green equals happy soup.
Is this soup freezer-safe with the squash in it?
Yes.
The squash holds up well compared to typical noodles. Texture stays pleasantly tender, not mushy—IMO, it’s a freezer win.
