Ingredients
- 1 ½ cups Arborio rice (short‑grain risotto rice)
- 8 oz (225 g) mixed cultivated mushrooms, cleaned and sliced (e.g., cremini, shiitake, oyster)
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 4 cups low‑sodium vegetable broth, kept warm
- ½ cup dry white wine (optional)
- 3 Tbsp unsalted butter, divided
- 2 Tbsp olive oil
- ½ cup freshly grated Parmesan cheese
- ¼ cup heavy cream (or a plant‑based alternative)
- Salt and freshly ground black pepper to taste
- Fresh parsley, chopped, for garnish
Method
- Prepare the broth – Heat the vegetable broth in a saucepan and keep it at a gentle simmer. This ensures the rice absorbs hot liquid throughout cooking.
- Sauté the mushrooms – In a large skillet, melt 1 Tbsp butter with the olive oil over medium heat. Add the sliced mushrooms, seasoning lightly with salt. Cook, stirring occasionally, until they release their moisture and turn golden, about 5‑7 minutes. Remove and set aside.
- Start the risotto base – In the same skillet, add the remaining 2 Tbsp butter. Toss in the diced onion and cook until translucent, 3‑4 minutes. Add the minced garlic and stir for another 30 seconds.
- Toast the rice – Sprinkle the Arborio rice over the onion‑garlic mixture. Stir constantly for 2‑3 minutes until the grains become lightly translucent around the edges. This toasting step helps the rice retain a creamy texture later.
- Deglaze with wine – If using wine, pour it in now and stir until the liquid is mostly absorbed. The acidity brightens the flavor and helps release any browned bits from the pan.
- Gradual broth addition – Ladle about ½ cup of the hot broth into the rice, stirring continuously. Once the liquid is almost fully absorbed, add another ½ cup. Continue this process, stirring frequently, for 18‑20 minutes. The rice should be tender yet retain a slight bite (al dente).
- Finish the dish – When the rice reaches the desired texture, stir in the sautéed mushrooms, grated Parmesan, and the heavy cream. Cook for another 2‑3 minutes, allowing everything to meld. Taste and adjust seasoning with salt and pepper.
- Serve – Spoon the risotto onto warm plates, garnish with chopped parsley and an extra sprinkle of Parmesan if desired. Serve immediately for the best creamy consistency.
Tips for Success
- Warm broth matters – Adding cold broth slows the cooking process and can produce uneven textures.
- Stirring frequency – Frequent stirring releases the rice’s starch, creating the characteristic creaminess of risotto. You don’t need to stir nonstop, but don’t let the rice sit untouched for long periods.
- Choosing mushrooms – Cultivated varieties provide reliable flavor and safety. Avoid wild mushrooms unless you are an expert forager.
- Texture check – The final risotto should flow like a thick soup when spooned; it should not be dry or clumpy.
A Little Mars Inspiration
Just as Mushroom 2 Mars envisions cultivating fungi in space, this humble risotto reminds us that with the right care, mushrooms can thrive anywhere—from a kitchen stove to a future Martian greenhouse.

Only eat mushrooms you bought from a trusted seller or grew yourself. Never eat a wild mushroom unless an expert has identified it. Cook mushrooms thoroughly and check ingredients for allergies.
