Start by washing and trimming the asparagus, then cut it into bite-sized pieces. Mince the garlic and grate the pecorino cheese freshly for the best flavor. Having everything ready makes cooking smoother and quicker.
Bring the vegetable stock to a gentle boil in a saucepan, then slowly whisk in the polenta. Stir continuously to avoid lumps and reduce heat to low. Let it cook until thick and creamy, stirring often to maintain a smooth texture.
Heat olive oil in a skillet and add minced garlic for a quick sauté. Toss in asparagus and cook until slightly tender but still crisp. Add peas and cook briefly to keep their vibrant color and sweetness intact.
Stir butter and grated pecorino into the cooked polenta until melted and creamy. Add lemon zest, salt, and pepper for seasoning. Gently fold in the sautéed vegetables or serve them on top for a layered presentation.
Spoon the creamy polenta into bowls and top with the asparagus and peas mixture. Finish with extra pecorino and a drizzle of olive oil. Serve immediately while warm for the best taste and texture.
