Creating the perfect Mushroom Risotto is straightforward if you follow these steps meticulously:

1. Prepare Broth: In a saucepan, heat the vegetable broth over low heat to keep it warm.
2. Sauté Aromatics: In a large skillet, heat olive oil and 1 tablespoon of butter over medium heat. Add the chopped onions and sauté until translucent (about 5 minutes).
3. Add Garlic: Stir in minced garlic and cook for another minute until fragrant.
4. Cook Mushrooms: Add sliced mushrooms to the skillet and cook until they are browned and tender (about 7 minutes). Set aside a few for garnish, if desired.
5. Add Rice: Stir in Arborio rice, coating it with the oil and cooking for 2-3 minutes until the rice is slightly translucent.
6. Pour Wine: Add white wine (or broth) and stir until fully absorbed.
7. Gradual Broth Addition: Begin adding the warm broth, one ladle at a time, stirring frequently. Wait until the liquid is mostly absorbed before adding more.
8. Cook: Continue this process for about 18-20 minutes, until the rice is creamy and al dente.
9. Finish with Cheese: Once the rice is cooked, remove the skillet from heat and stir in the remaining tablespoon of butter and grated Parmesan cheese. Season with salt and pepper to taste.
10. Garnish and Serve: Plate your Mushroom Risotto, garnishing with reserved mushrooms and fresh herbs, if desired.

These steps will guide you in creating an incredible Mushroom Risotto that not only tastes good but also warms the heart.
