Creating Mushroom Parmesan Shrimp Risotto can be a delightful experience if you follow these simple steps:

1. Prepare the Broth: In a saucepan, heat the chicken or vegetable broth over medium heat. Keep it warm but not boiling.
2. Sauté the Aromatics: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Add the minced garlic and cook for an additional minute.
3. Cook the Mushrooms: Add the sliced mushrooms to the skillet. Sauté until they are tender and browned, approximately 5-7 minutes. Season with salt and pepper.
4. Add the Rice: Stir in the arborio rice, coating it with the oil and allowing it to toast slightly for about 2 minutes.
5. Deglaze with Wine: If using, pour in the white wine and stir until it has mostly evaporated, about 2-3 minutes.
6. Incorporate Broth Gradually: Begin adding the warm broth, one ladle at a time, stirring frequently. Wait until most of the liquid is absorbed before adding the next ladle. Repeat until the rice is creamy and al dente, about 18-20 minutes.
7. Cook the Shrimp: In the last 5 minutes of cooking, stir in the shrimp. Cook until they turn pink and opaque.
8. Finish with Cheese and Butter: Remove the skillet from heat and stir in the grated Parmesan cheese and butter. Adjust seasoning with salt and pepper, to taste.
9. Garnish: Serve immediately, garnished with freshly chopped parsley.
