Warm your broth on the stove so it's steaming when you need it. In a large pot, heat the olive oil and 2 tablespoons of butter over medium-high heat, then add the garlic and cook until fragrant. Stir in the rice and toast it for a couple of minutes until it turns lightly golden.
Pour in the wine along with a pinch of salt, and let it cook down until it's absorbed into the rice. Add most of the warm broth, bring everything to a boil, then cover the pot, lower the heat, and let it simmer untouched for about 15 minutes. This is the "no-stir" magic at work.
Once the rice is tender, uncover the pot and stir in the remaining broth, lemon juice, and parmesan. Keep stirring gently for a few minutes until the mixture turns glossy and thick. This short stirring window is really the only active step, and it's what makes the risotto so creamy.
Drop in the cubed brie and stir just until it melts into the rice. Pull the pot off the heat right away so the cheese doesn't turn stringy. Taste and adjust the salt, and thin it out with a splash of warm broth if it feels too thick.
While the rice simmers, heat butter and olive oil in a skillet with garlic, lemon zest, and thyme. Add the chopped asparagus, season with salt and pepper, and cook until it's just tender with lightly caramelized edges.
Spoon the warm risotto into bowls right away and top with the lemon butter asparagus. Finish with a crack of black pepper. Since risotto keeps thickening as it sits, this is a dish best enjoyed the moment it's ready.
