Start by preheating your oven to 400°F (200°C) to ensure even cooking.
Gather all your ingredients. Trim the asparagus and grate the garlic and Parmesan cheese.
In your oven-safe dish, combine the arborio rice, asparagus, grated garlic, 4 cups of vegetable broth, and kosher salt. Stir everything together.
Cover the dish tightly with aluminum foil and bake for 25 minutes.
Remove the dish from the oven. Stir in the thawed peas and the remaining 1 cup of broth.
Add in the freshly grated Parmesan cheese until it melts into the risotto.
Return the dish to the oven uncovered and bake for an additional 10-15 minutes.
Let the risotto sit for a few minutes before serving warm, garnished with extra Parmesan cheese and black pepper.
