Instructions

  1. Step 1: Heat 3 tbsp olive oil in a large skillet over medium heat. Add 1 medium finely chopped yellow onion and sauté for 4 minutes until translucent. Stir in 3 minced garlic cloves and 8 oz sliced cremini mushrooms, cooking for 5 minutes until mushrooms are tender and golden.
  2. Step 2: Add 1 1/2 cups Arborio rice to the skillet, stirring to coat each grain with oil and cook for 2 minutes until edges become translucent.
  3. Step 3: Pour in 1/2 cup dry white wine and stir continuously until fully absorbed. Begin adding warm vegetable broth, 1/2 cup at a time, stirring constantly and allowing liquid to absorb before adding more, continuing for 20 minutes until rice is creamy and tender.
  4. Step 4: Stir in 3 cups roughly chopped fresh spinach and cook for 2 minutes until wilted. Remove from heat, then fold in 2 tbsp unsalted butter and 1/2 cup freshly grated Parmesan cheese. Season with 1 tsp salt and 1/2 tsp black pepper, stirring until melted and creamy. Serve immediately.

Can I substitute ingredients in Underground Mushroom and Spinach Risotto?

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 Underground Mushroom and Spinach Risotto 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.
