  • 1 Croissant Bread Loaf (large croissant loaf, sliced into 6 halves)
  • 4 Tbsp Unsalted Butter (softened) (for garlic‑butter spread)

Instructions

  1. Prepare Vegetables

    Wash all produce. Roughly chop the tomatoes, red bell pepper (seeded), sweet onion, and leave the garlic cloves whole. Set aside.

    Time: PT15M

  2. Roast Vegetables

    Line a sheet pan with aluminum foil. Toss the chopped tomatoes, bell pepper, onion, and whole garlic cloves with avocado oil, salt, pepper, and a handful of torn basil leaves. Spread in an even layer and roast in a pre‑heated oven at 400°F for 35 minutes, turning once halfway through, until charred and fragrant.

    Time: PT35M

    Temperature: 400°F

  3. Transfer and Simmer

    Remove the roasted vegetables from the pan. Discard the skins and garlic if desired. In a large pot, melt 2 Tbsp butter over medium heat, then add the roasted veggies, fire‑roasted crushed tomatoes, vegetable broth, Italian herb seasoning, and crushed red pepper flakes. Bring to a gentle simmer and cook for 15 minutes, stirring occasionally.

    Time: PT15M

    Temperature: medium heat

  4. Blend the Soup

    Using an immersion blender, blend the soup directly in the pot until completely smooth (about 2‑3 minutes). If using a countertop blender, carefully ladle hot soup in batches, covering the lid with a kitchen towel, and blend for 1‑2 minutes. Return the blended soup to the pot.

    Time: PT5M

  5. Finish with Cream

    Stir in ½ cup heavy whipping cream, adjust salt and pepper to taste, and let the soup simmer gently for another 5 minutes.

    Time: PT5M

    Temperature: low simmer

  6. Make Garlic‑Butter Spread

    In a small bowl, combine softened butter, minced garlic, chopped basil, and a pinch of salt. Mix until smooth.

    Time: PT5M

  7. Assemble Croissant Grilled Cheese

    Slice the croissant loaf horizontally into 6 halves. Spread a thin layer of the garlic‑butter mixture on each cut side. Evenly distribute the shredded cheese blend on the bottom half, then place the top half over the cheese.

    Time: PT5M

  8. Cook Grilled Cheese

    Heat a skillet over medium heat and lightly coat with non‑stick spray or a dab of butter. Place the assembled sandwich in the pan, cooking 2 minutes per side until golden brown and the cheese melts. For extra melt, cover the pan with a lid for the last minute and add a tiny splash of water to create steam.

    Time: PT5M

    Temperature: medium heat

  9. Plate and Garnish

    Ladle soup into bowls, swirl a drizzle of heavy cream and balsamic glaze on top, and garnish with fresh basil leaves. Serve each bowl with a hot croissant grilled cheese, cut into triangles if desired.

    Time: PT2M
