Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Toss 12 oz sliced cremini mushrooms and 5 whole garlic cloves with 2 tbsp olive oil and 1/2 tsp salt on a baking sheet. Roast for 20 minutes until mushrooms are golden and garlic is soft.
  2. Step 2: Meanwhile, heat 1 tbsp olive oil in a large pot over medium heat. Add 1 medium diced yellow onion and 1 tsp fresh thyme leaves, sauté for 5-6 minutes until onion is translucent and fragrant.
  3. Step 3: Add the roasted mushrooms and garlic (squeezing garlic out of skins) to the pot along with 4 cups vegetable broth and bring to a simmer for 10 minutes.
  4. Step 4: Use an immersion blender to puree the soup until smooth and creamy, or carefully transfer to a blender in batches.
  5. Step 5: Stir in 1/2 cup heavy cream and season with 1/2 tsp salt and 1/2 tsp black pepper. Warm through over low heat for 3 minutes without boiling.
  6. Step 6: Serve hot with an optional drizzle of cream or fresh thyme sprig.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep cremini mushrooms from drying out.

Can I substitute ingredients in Roasted Mac Mini Mushroom and Garlic Soup?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Roasted Mac Mini Mushroom and Garlic Soup for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
