Riverside Resort's Tomato Bisque

I was at WDW's Riverside Resort a few days ago, and had the most amazing tomato bisque soup. It was so thick, creamy and full of tomatoey flavor that I had several bowls of it. After coming home I found a few different recipes for Disney tomato bisque soups; after looking at the ingredients, I'm sure this is the one I had.

• Ready In: 1 hr 30 mins
• Serves: 16

Ingredients

• 4 (16 ounce) cans  of peeled plum tomatoes (best quality)
• 8  ounces  diced celery
• 8  ounces  diced onions
• 8  ounces  diced carrots
• 1  quart heavy cream, gently heated
• 2  ounces fresh basil, chopped
•  salt
•  white pepper, to taste
• 6  ounces tomato paste

Directions

1. Preheat oven to 350 degrees F. Drain liquid from tomatoes and reserve.
2. Place plum tomatoes on a sheet pan sprayed lightly with Pam, and roast in the oven for 20-30 minutes. Meanwhile, over medium-low heat, saute onions, celery and carrots in a stockpot until translucent, approximately 10 minutes, or just until veggies are tender-crisp.
3. Remove roasted tomatoes and allow to cool for a few minutes. Add them to the stockpot along with the reserved tomato juice and tomato paste and stir until combined.
4. Cook for 30-40 minutes. Start gently warming the heavy cream. Meanwhile, puree stockpot mixture, and then add the warmed cream. Finish with salt and pepper to taste.
5. Add fresh chopped basil at the end.
