Melt half the butter in a large skillet over medium heat. Add diced onion and minced garlic, cooking until the onion becomes translucent. This step forms the aromatic foundation for your risotto.
Add arborio rice to the skillet and stir for a minute so it’s coated in butter. Pour in the white wine and stir until mostly absorbed, scraping up any browned bits to deepen the flavor.
Add warm chicken stock one cup at a time, stirring frequently. Let the rice absorb most of the liquid before adding more. This creates the creamy texture that makes risotto irresistible.
Once the rice is tender but still slightly firm, swirl in the remaining butter and grated parmesan. Season with salt to taste. This final step makes the risotto luxuriously creamy.
Grill the corn and slice the kernels off the cob. Mix with halved cherry tomatoes, basil, lemon juice, salt, and pepper. Keep this salad separate until serving to maintain freshness.
Spoon the risotto onto plates or a serving dish, then pile the corn and tomato salad on top. The contrast of creamy rice and fresh salad is what makes this dish shine.
