Okay, Iām just gonna say itāthis might be the coziest, dreamiest recipe Iāve ever made. Weāre talkinā about a bowl of velvety, roasted tomato soup loaded with caramelized veggies, a creamy swirl of heavy cream and Parmesan, and THEN⦠topped off with smoky bacon bits, basil, and cheese. Ohāand you have to serve it with a melty grilled cheese on the side. Thatās not optional.

š„ Step-by-Step Instructions
1. Roast Your Veggies to Build Big Flavor
Preheat your oven to 400°F (200°C). Chop the large tomatoes, bell pepper, and onion into chunks. Toss everythingāincluding a pint of cherry tomatoesāinto a roasting dish. Drizzle generously with olive oil and season with salt, pepper, garlic powder, onion powder, paprika, and dried basil.
Cut the tops off two heads of garlic, drizzle with olive oil, and wrap them in foil. Add them to the pan and roast everything for 45 minutes to 1 hour until caramelized and golden.
š§ Pro tip: Roasting the garlic brings out a sweet, mellow flavor thatās unreal in soup!
2. SautƩ the Aromatics
In a large soup pot, melt 3 tbsp of butter with a dash of olive oil. Add in ½ a diced onion and sautĆ© with salt and pepper until translucent. Toss in the minced garlic and cook just until fragrantāabout 1 minute.
Then stir in your tomato paste. Let it darken slightly in the pan; this caramelization step adds a deep umami flavor thatās seriously next-level. Add the tomato sauce and give it a good mix.
3. Add the Roasted Veggies & Blend
Once your veggies are out of the oven (donāt forget the garlic!), squeeze the roasted garlic cloves right into your pot. Add the rest of the roasted veggies and stir to combine.
Pour in your broth and season again with the same herbs you used earlierāgarlic/onion powder, paprika, and dried basil. Let it all simmer for about 5ā10 minutes so the flavors meld.
Now itās time to blend! Use an immersion blender to blend the soup until silky smooth. You can also use a regular blenderājust work in batches and be careful with the heat.
4. Finish with Cream, Cheese, and Herbs
Bring your soup to a gentle simmer and add the heavy cream. If youāre using a parmesan rind (DO IT!!), nowās the time to toss it in. Let everything simmer for 20ā30 minutes, then fish out the rind.
Stir in the grated Parmesan and a handful of torn fresh basil leaves. Taste and adjust seasoning as needed.
5. Serve & Garnish Like a Pro
Ladle your soup into bowls and go wild with the toppings. I love adding a swirl of heavy cream, more grated cheese, a sprinkle of fresh basil, and crispy bacon bits for some crunch and smokiness.
And of course⦠serve with a grilled cheese sandwich for dunking. Crispy golden edges, gooey center⦠I mean, does it get better?

š§ Grilled Cheese Ideas (Level It Up!)
You can go classic or totally gourmet with these combos:
- Classic: White bread + sharp cheddar
- Grown-Up: Sourdough + fontina + caramelized onions
- Spicy: JalapeƱo cheddar + hot honey drizzle
- Fancy: Mozzarella + pesto + tomato slices
š” Tips for Success
- Roast longer = deeper flavor. Donāt rush the roasting! Let those veggies get golden and caramelized.
- Parm rind magic. It adds richness without extra saltājust remove before serving!
- Use a high-powered blender for the smoothest texture if you donāt have an immersion blender.
- Make it dairy-free? Swap butter for olive oil, cream for coconut cream, and skip the cheeseāor use a dairy-free version.
š„ Storage & Reheating
- Fridge: Store leftovers in an airtight container for up to 4 days.
- Freezer: Freeze for up to 3 months. Reheat gently over the stove, adding a splash of broth or cream to revive the texture.
