This creamy turkey soup transforms leftover turkey into a restaurant-quality meal with tender chunks of meat, aromatic vegetables, and a velvety cream broth. The classic roux-thickened base creates a silky texture that clings to every ingredient, while fresh thyme and garlic add layers of comforting flavor perfect for cold days.
Dice the onion, carrots, and celery into uniform 1/4-inch pieces. Peel and cube the potatoes into 1/2-inch pieces, placing them in cold water to prevent browning, and mince the garlic finely.
Melt the butter in a Dutch oven over medium heat, then add the diced onion, carrots, and celery. Cook for 8-10 minutes, stirring occasionally, until vegetables soften and the onion becomes translucent, then add garlic and cook for 30 seconds until fragrant.
Sprinkle the flour evenly over the vegetables and stir to coat thoroughly. Continue stirring and cook for 2-3 minutes to eliminate the raw flour taste, creating a thick paste-like roux.
Slowly pour in 2 cups of broth while stirring constantly to prevent lumps, then add the remaining 4 cups of broth. Add the drained potatoes, bay leaf, and thyme, then bring to a boil over medium-high heat before reducing to a simmer.
Allow the soup to simmer gently for 15-20 minutes, stirring every 5 minutes, until the potatoes are fork-tender. Skim off any foam that rises to the surface and adjust salt and pepper to taste.
Stir in the cooked turkey pieces and frozen peas, then slowly pour in the heavy cream while stirring. Add the garlic powder and allow the soup to heat through for 5 minutes without boiling.
Remove the bay leaf and discard it. Taste and adjust seasonings as needed, then ladle the hot soup into bowls and garnish with freshly chopped parsley.
Notes
Use a combination of dark and white turkey meat for the best texture and flavor balance.
Don't skip cooking the roux properly for 2-3 minutes to eliminate any raw flour taste.
Keep the heat at medium-low after adding cream to prevent curdling; never let it boil.
For homemade turkey stock, simmer the turkey carcass with aromatics for 2 hours for richer flavor.
For a thicker soup, mash some potatoes against the pot or blend 1-2 cups with an immersion blender.
Store leftovers in airtight containers in the refrigerator for 3-4 days; soup freezes well for up to 3 months.
When reheating, warm over medium-low heat and add a splash of broth if the soup has thickened too much.
Substitute rotisserie chicken for turkey if making this recipe outside of holiday season.
For a lighter version, use half-and-half instead of heavy cream and thicken with a cornstarch slurry.
Add wild rice or egg noodles for a heartier variation; cook noodles in the last 10 minutes.
