Place the stock in a small pot and heat over medium low. You want the stock to be warm when adding it to the risotto so that the temperature change does not affect the rice.
Make your pesto if it is not done already.
Halve the cherry tomatoes and place in a small bowl with the pearlini mozzarella. Drizzle with olive oil. Add the 1/4 teaspoon dried basil and a pinch of salt. Combine and refrigerate to marinate while cooking the risotto.
In a large pot, melt 3 tablespoons of the butter over medium heat. When melted, add the red onion. Cook until the onion is translucent but not yet browning, approximately 3-5 minutes.
Add the rice and stir. Continue cooking to slightly toast the rice until it is just starting to show a little brown color, approximately 3-5 minutes.
Add the white wine to the pot. Cook until the rice is almost dry, where most of the wine has been absorbed.
Add one cup of stock to the rice. Stir continuously until most of the stock has been absorbed. Repeat this process 1/2 cup of stock at a time until the rice is cooked thoroughly. You want the rice to have just a little bit of bite left so that it is not completely mushy. Depending on your rice, you may need more or less stock for the right consistency so start tasting the rice after 4 cups.
When your rice is cooked through (approximately 30-40 minutes), remove the pot from the heat. Add the rest of the butter, the Parmesan cheese, and pesto sauce. It is important to do this before adding salt and pepper because the cheese is salty. Stir to combine.
Taste the risotto and season with additional pesto, salt, and pepper as desired. Top the risotto with the tomato and mozzarella mixture (if you mix it in, the mozzarella will melt). Garnish with toasted pine nuts if desired for an extra crunch. Serve immediately.
