Warm the olive oil in a heavy pot over medium heat.
Sauté onion, carrots, and celery until slightly softened, about 5–6 minutes.
Stir in mushrooms and cook until they release juices and brown, about 5 minutes.
Add garlic and cook 30 seconds until fragrant.
Sprinkle flour over the vegetables and stir for 1 minute to form a light roux.
Slowly pour in the broth, stirring constantly to smooth out any lumps.
Add potatoes, soy sauce, thyme, rosemary, salt, and pepper. Bring to a gentle simmer.
Cover and cook until potatoes are just tender, 12–15 minutes.
Mix dumplings: whisk flour, baking powder, and salt. Stir in milk, butter, and parsley until just combined.
Stir peas into the simmering stew. Drop heaping tablespoons of dough over the surface, leaving space.
Cover tightly and steam dumplings over a low simmer until puffed and cooked through, 12–15 minutes. Avoid lifting the lid for the first 10 minutes.
Taste and adjust seasoning. Finish with chopped parsley and ladle into bowls.
Notes
Make it dairy-free: swap the butter for olive oil and use unsweetened plant milk. For extra flavor, add a dash of hot sauce or a splash of white wine when deglazing.Storage: Refrigerate up to 4 days. Reheat gently with a splash of broth to loosen the stew and keep dumplings tender. Dumplings are best reheated covered to trap steam.This recipe is an original creation inspired by classic Veggie Dumpling Stew Recipes flavors.
