Quick Stovetop Mac & Cheese with Peas

Bring a large saucepan of water to a boil. Cook pasta according to the package instructions, adding peas during the last 2 minutes of cooking time. Drain.

Whisk 1/4 cup milk, flour, lemon zest, salt and pepper in a small bowl; place near the stove. Add the remaining 1 1/2 cups milk to the saucepan. Heat over medium-high heat until just simmering. Add the flour mixture and reduce heat to medium-low. Cook, whisking constantly, until thickened, 1 to 2 minutes. Remove from heat and whisk in fontina, cream cheese and vinegar until the cream cheese is melted. Stir the pasta and peas into the sauce. Serve topped with basil.
