🛒 Ingredients

- 2 red bell peppers, seeded, cut into large pieces
- 2 medium carrots, peeled, cut into chunks
- 1 small sweet potato, peeled, cubed (about 1½ cups)
- 1 small onion, quartered
- 1 head garlic, top trimmed to expose cloves
- 2 tbsp olive oil, plus more for garlic
- 1 tsp Italian seasoning
- ½ tsp kosher salt, plus more to taste
- ¼ tsp black pepper
- 28 oz crushed or whole peeled tomatoes (if whole, crush by hand)
- ½–¾ cup low-sodium vegetable or chicken broth (start with ½ cup)
- ¼–½ cup cream or half-and-half (start with ¼ cup; add for extra silk)
- ¼ cup freshly grated Parmesan (optional, for savory depth)
- 1–2 tbsp butter (optional, finishes glossy)
- Pinch red pepper flakes (optional, for gentle warmth)
- Fresh basil or parsley, chopped, to finish
Dairy-free option: use cashew milk instead of cream, skip Parmesan, and finish with 1 tsp olive oil or plant butter for the same sheen.
🔥 Roast, Blend & Make It Silky (Step by Step)
1) Roast the veggies
Heat oven to 425°F (218°C). On a parchment-lined sheet pan, toss peppers, carrots, sweet potato, onion with 2 tbsp olive oil, Italian seasoning, salt, and pepper. Place the garlic head on a small foil square, drizzle with a bit of oil, wrap loosely, and set on the pan. Roast 25–30 minutes, stirring once, until veggies are caramelized and tender. Let the garlic cool; squeeze out the soft cloves.
2) Simmer the tomatoes
In a large sauté pan, add crushed/peeled tomatoes, ½ cup broth, and red pepper flakes (if using). Bring to a gentle simmer over medium-low while the vegetables finish roasting (5–10 minutes). This rounds off acidity.
3) Blend ultra-smooth
Add the roasted veggies and squeezed garlic to the pan. Remove from heat. Immersion blend until completely silky (or blend in batches—vent the lid). If needed, add splashes of broth to reach your ideal thickness.
4) Make it creamy
Return to low heat. Stir in ¼ cup cream and Parmesan (if using). Warm gently 1–2 minutes (don’t boil) until glossy. Swirl in butter if you’d like extra richness. Taste and adjust salt/pepper.
5) Serve or store
Finish with basil/parsley. Toss with hot pasta, use in lasagna or baked ziti, or cool and pack for the fridge/freezer.
🍝 Yield & Use
Makes about 4½–5 cups—enough to coat 1 to 1¼ lbs pasta (serves 6–8), or two 9×9 bakes. Freezes beautifully for fast, healthy “hidden veggie” nights.

🧑🍳 Pro Tips for Peak Flavor
- Roast to caramelize. Color = sweetness. Don’t pull veggies too soon.
- Balance acidity. A splash of broth and a minute of simmering smooth sharp edges.
- Add dairy last. Keep heat low to prevent splitting; never hard-boil after cream goes in.
- Season in layers. Taste after blending and again after adding cream/cheese.
🌿 Easy Variations
- Red Pepper Love: Use 3 peppers for a rosier, sweeter sauce.
- Herby Finish: Stir in pesto or a handful of chopped basil off-heat.
- Protein Boost: Simmer mini turkey/chicken meatballs in the finished sauce.
- All-Dairy-Free: Cashew milk + 1–2 tbsp nutritional yeast for savory depth.
- Smoky Kick: Add a pinch of smoked paprika with the tomatoes.
🥗 Serving Ideas

- Toss with rigatoni, penne, or shells; finish with Parmesan and basil.
- Spoon over cheese tortellini or gnocchi for weeknight indulgence.
- Layer into lasagna or pour over stuffed shells.
- Use as a base for chicken parmesan or meatball subs.
- Thicken slightly and spread on pizza.
🧊 Storage & Meal Prep
- Fridge: Cool completely; store up to 5 days.
- Freeze: Portion in containers/bags up to 3 months.
- Reheat: Warm gently on low; loosen with a splash of broth or milk. Avoid boiling after adding dairy.
🛠️ Troubleshooting
- Too thick? Whisk in warm broth until just right.
- Too thin? Simmer a few minutes to reduce, or blend in 1–2 tbsp tomato paste.
- Grainy after cheese? Remove from heat, add cheese gradually, stir to smooth.
- Too tangy? A pinch of sugar/honey, an extra spoon of cream, or a small knob of butter rounds it out.
- Kids spot “green”? Blend fully and add herbs only as garnish—or skip the garnish.
❓FAQs (Quick Answers)
Fresh tomatoes instead of canned?
Yes—use 2½–3 lbs peeled, seeded, chopped. Roast them alongside the veg or simmer longer to concentrate.
Can I skip cream?
Sure—finish with 1–2 tbsp butter or olive oil; or use cashew milk for a lighter creaminess.
Best pasta shape?
Sauce-clingers like rigatoni, penne, rotini, or shells. Long pasta works too—the sauce is very clingy.
Add spinach?
Wilt 2 cups baby spinach into the hot sauce or blend it in for a deeper color.
Make it spicy?
Bump red pepper flakes or add a pinch of cayenne when simmering tomatoes.
