Creamy Mushroom Soup

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup chopped mushrooms
2 tablespoons butter
½ teaspoon minced garlic
1 teaspoon onion powder
½ teaspoon salt
⅛ teaspoon ground pepper
6 tablespoons gluten‑free all‑purpose flour
2 cups gluten‑free chicken broth
1 cup milk

Directions

In a medium saucepan or skillet over medium heat, melt the butter. Add the minced garlic and sauté briefly until fragrant—about 30 seconds.
Stir in the chopped mushrooms. Sauté until they begin to soften and release moisture.
Sprinkle in the onion powder, salt, and pepper, mixing to coat the mushrooms.
Sprinkle the gluten‑free flour evenly over the mixture, stirring constantly to form a roux—cook for about 1 minute to eliminate raw flour flavor.
Gradually whisk in the gluten‑free chicken broth, a little at a time, ensuring a smooth consistency as you go.
Pour in the milk while whisking continually. Increase heat slightly and bring to a gentle simmer. Continue whisking until the sauce thickens to your desired consistency.
Taste and adjust seasoning as needed.
Serve warm over your favorite dishes.

Servings and timing

Servings: About 4 medium-sized portions (depending on how it’s used)
Prep time: ~5 minutes
Cook time: ~10 minutes
Total time: ~15 minutes

Variations

Richer and thicker: Replace milk with heavy cream or half-and-half.
Extra umami: Add a splash of gluten‑free tamari or Worcestershire—many recipes use these for depth
Speedier thickening or lighter version: Use a cornstarch or arrowroot slurry instead of flour: mix 1 Tbsp slurry with cold water, then whisk into hot liquid
Herby notes: Stir in fresh or dried herbs like thyme, parsley, or sage.
Vegan/dairy‑free swap: Use a non‑dairy milk (like almond or oat) and vegan butter—many mushroom gravy recipes adjust well

Storage/Reheating

Storage: Let cool, then store in an airtight container in the refrigerator for up to 2–3 days.
Reheating: Gently reheat on low heat, whisking to restore smooth consistency. If too thick, thin with a splash of milk or broth. Avoid high heat to prevent separation.

FAQs

What if the sauce is too thin?

Simmer a bit longer to reduce and thicken, or whisk in a small cornstarch slurry (1 Tbsp cornstarch + 2 Tbsp cold water)

Can I use heavy cream instead of milk?

Yes—heavy cream yields a richer, silkier sauce and can reduce more slowly.

Are there alternative gluten‑free thickeners I can use?

Yes, cornstarch, arrowroot, tapioca, potato starch, or sweet rice flour work well—each used as a slurry

Can I make this vegan?

Absolutely—use plant‑based milk and butter alternatives. Vegan mushroom gravy recipes follow similar steps

Can I add wine for extra flavor?

Yes—a splash of white wine added with the broth can add complexity, similar to many mushroom sauces .

Is onion powder necessary?

No—but it adds depth. You can substitute a bit of finely diced onion or skip it entirely if preferred.

Can I make this ahead?

Yes—prepare and refrigerate, then reheat gently when serving.

Will it re‑thicken after cooling?

Yes—the sauce often thickens as it cools. Thin with milk or broth when reheating.

Can I use this as a gravy over meat?

Definitely—it works as a gravy for poultry, beef, or gluten‑free mashed potatoes.

Any tips to avoid lumps?

Whisk continuously when adding broth and milk, and add liquids gradually. Slurry must be mixed with cold water before whisking into hot sauce .
