The Best Roasted Tomato Basil Soup

Ingredients

• 2 1/4 lbs Roma tomatoes , halved lengthwise
• 1 1/4 lbs Cherry tomatoes
• 4 1/2 Tbsp olive oil
• Salt and freshly ground black pepper
• 8 cloves garlic , peeled and left whole
• 2 small yellow onions , sliced just under 1/2-inch thick
• 2 cups (32g) lightly packed fresh basil leaves
• 4 - 5 cups low-sodium vegetable broth
• Grilled cheese croutons (optional), see notes

Instructions

1. Preheat oven to 425 degrees. Place tomatoes on a rimmed baking sheet and toss with 3 Tbsp olive oil then season with salt and pepper (place Roma halves cut side upright). 
2. Place onion slices and garlic on a rimmed half sheet and toss brush with remaining 1 1/2 Tbsp olive oil on all sides, sprinkle with salt and pepper. Place baking sheet with tomatoes and half sheet with onions in oven side by side and roast onions 30 - 35 minutes until edges are golden, and tomatoes 40 - 45 minutes until golden. Peel away any burnt papery layers of onions if there are any. 
3. Pull peels from tomatoes (I didn't do this with mine but later wished I would have so I'd recommend it so the soup isn't loaded with peels. If you want some peel then I'd peel at least half). Pour onions and tomatoes into a large pot. 
4. Add 4 cups vegetable broth and the basil. Season with salt and pepper to taste. Bring to a boil then reduce heat and simmer 20 minutes, adding an additional 1 cup vegetable broth to thin as desired. Blend soup with an immersion blender or in small batches in a blender (only fill blender half full).
5.  Serve warm topped with grilled cheese croutons if desired.

Recipe Notes
For the grilled cheese croutons use 6 slices of hearty sandwich bread, brush outsides of all slices with 1/2 Tbsp of butter on each. Sprinkle about 1/2 cup (2 oz) shredded mozzarella or cheddar over non-buttered sides of three slices. Top with remaining 3 slices of bread with buttered side up. Cook in a non-stick skillet over medium heat, reducing to medium-low as needed, until bottom is golden brown. Flip and cook opposite side until golden. Cool just slightly then cut into squares.
