A creamy, rich mushroom risotto made quickly in the Instant Pot, featuring arborio rice, cremini mushrooms, spinach, peas, and Parmesan cheese. Perfect for a comforting and easy weeknight meal.

  • Total Time: 35 minutes
  • Yield: 6 servings 1x

Ingredients

Scale
  • 4 tablespoons unsalted butter, divided
  • 3 cloves garlic, minced
  • 1 onion, diced
  • 8 ounces cremini mushrooms, thinly sliced
  • Kosher salt and freshly ground black pepper, to taste
  • 2 cups chicken broth
  • 1 cup arborio rice
  • 1/4 teaspoon dried thyme
  • 2 cups baby spinach
  • 3/4 cup frozen peas, thawed
  • 1/4 cup freshly grated Parmesan

Instructions

  1. Set your 6-quart Instant Pot on high sauté. Melt 2 tablespoons butter, then add the garlic and onion. Cook, stirring frequently, until the onions turn translucent and sweet, about 3-4 minutes.
  2. Add the mushrooms and cook, stirring every now and then, until they’re tender and juicy, about 3-4 minutes. Season with salt and pepper to your taste.
  3. Pour in the chicken broth, then stir in the rice and thyme. Lock the lid, set to manual/high pressure, and cook for 6 minutes. When done, do a quick pressure release as per your Instant Pot’s instructions.
  4. Stir in the spinach and remaining 2 tablespoons butter until the spinach wilts, about 2 minutes. Then fold in peas and Parmesan, warming through for about 30 seconds to 1 minute.
  5. Serve right away for the best texture and creaminess.

Notes

Use a 6-quart Instant Pot for best results., Do not rinse the arborio rice to preserve starch for creaminess., For a vegetarian version, substitute chicken broth with vegetable broth., To reheat leftovers, add broth and gently warm to maintain creaminess., Mix mushroom types as desired (baby bella, shiitake, oyster, etc.)., Optional add-ins: white wine deglaze after sautéing for added flavor., Avoid long-grain rice such as jasmine or basmati; arborio is preferred for creaminess., Quick release pressure to prevent overcooking and maintain al dente texture., Butter and Parmesan add richness and creaminess, but can be substituted with dairy-free options if needed.
