In a large dutch oven, over med-high heat, sauté the diced bacon with the butter.
Add in the onion, carrot, celery, and cauliflower. Continue to sauté for just a few minutes, until the veggies begin to soften. Add the tomato paste, stirring until a dark red color develops.
Add the clam juice, chicken broth, tomato sauce, bay leaves, dried thyme. Simmer until the veggies are tender.
Add heavy cream to the chowder mixture and bring it back to a simmer.
Add in the drained and rinsed clams. Cook until the clams are warmed through.
Remove the bay leaves and enjoy!
Notes
You can swap out the cauliflower with potatoes. They are interchangeable and both are delicious!
