My grandmother would make lobster bisque all the time, so I've always thought of it as comfort food. If you don't care to cook live lobsters, they can usually be cooked where you buy them. Just be sure to say that you want to keep the shells; they are the key to the most delicious soup! —James Schend, Dairy Freed
In a Dutch oven, add 2 inches water; bring to a rolling boil. Add lobsters, cover, and steam for 8 minutes. Remove lobsters, reserving liquid. When cool enough to handle, remove meat from claws and tail, reserving any juices; refrigerate meat and juices.
In the same Dutch oven, cook carrots and onion in butter over medium-high heat until tender, 5-8 minutes. Stir in tomato paste and cook until it starts to caramelize, about 5 minutes. Add garlic; cook 1 minute. Stir in wine and simmer until reduced by half. Add lobster shells, bodies, reserved cooking liquid, reserved lobster juices and stock. Bring mixture to a simmer; cook 1 hour. Strain mixture, pressing to extract as much liquid as possible; discard shells and solids.
Return liquid to Dutch oven. Add rice and cook until extremely soft, 25-30 minutes. Puree in a blender until smooth. Add cream, thyme, salt and pepper. Bring mixture to very low simmer; add reserved lobster meat and cook until heated through. If desired, sprinkle with additional ground pepper and parsley.
