Large Pot or Dutch Oven For sautéing and simmering the bisque. A heavy-bottomed pot ensures even heat distribution.
Blender or immersion blender To achieve that signature creamy texture of a bisque soup. If you don’t have an immersion blender, a regular high-speed blender works (just be careful with the heat).
Baking Sheet or Skillet For toasting the grilled cheese bites. A skillet gives more control, but a baking sheet in the oven is great for batch cooking.
Fine mesh strainer (optional) If you want your tomato bisque soup ultra-smooth and seed-free.
Knife and Cutting Board For prepping your ingredients.

Instructions
Step 1: Roast the Tomatoes and Aromatics
Preheat your oven to 400°F (200°C). Spread quartered fresh tomatoes and chopped onions on a baking sheet. Drizzle with olive oil and season with a pinch of salt and pepper. Roast for about 25 minutes, until the tomatoes are soft and slightly caramelized. This step intensifies the natural sweetness of the tomatoes and is what sets a good tomato bisque soup apart from the rest.
Step 2: Sauté the Garlic and Add Base Flavors
In a large pot or Dutch oven, melt butter over medium heat. Add minced garlic and cook for about 30 seconds until fragrant. Stir in the tomato paste and allow it to caramelize for 1–2 minutes. This adds depth to the soup base.
Step 3: Simmer the Soup
Add the roasted tomatoes and onions to the pot. Pour in the broth, add dried oregano, crushed red pepper flakes (if using), and sugar. Stir to combine. Bring everything to a boil, then reduce heat and simmer uncovered for 15 minutes.
Step 4: Blend to Bisque Perfection
Remove the pot from heat. Add fresh basil and use an immersion blender to blend the soup until smooth and creamy. If using a regular blender, do this in batches, venting the lid slightly to let steam escape. Optional: For an ultra-smooth finish, strain through a fine mesh sieve to remove tomato skins and seeds.
Step 5: Creamify and Season
Return the soup to the pot. Stir in the heavy cream and balsamic vinegar. Simmer for 5 more minutes. Taste and adjust seasoning with more salt or pepper as needed. You now have a lush, creamy tomato bisque soup that’s bursting with layered flavor.
Step 6: Make the Grilled Cheese Bites
While the soup simmers, assemble your grilled cheese. Butter one side of each bread slice. Place cheddar and mozzarella on the unbuttered side of two slices, then top with the remaining bread, buttered side up. Toast in a skillet over medium heat until golden and crispy, about 3–4 minutes per side. Let them rest for 1–2 minutes, then cut into bite-sized squares.
Step 7: Serve and Enjoy
Ladle the hot bisque into bowls and top with a drizzle of cream or a swirl of olive oil if desired. Scatter grilled cheese bites over the top or serve them on the side for dipping. This is your creamy tomato bisque soup moment—savor it.
