Bring a large pot of water to a rapid boil and add a generous pinch of kosher salt. Stir in the pasta and cook just to al dente, according to package instructions.
kosher salt and black pepper, 8-10 ounces pappardelle or other pasta
Chop all the veggies and mince the garlic.
1/4 medium yellow onion, 1 small zucchini or yellow squash, 1/2 small bunch asparagus, 1/2 bell pepper, 1/2 cup frozen peas, 3-4 cloves garlic
Measure and set the cream out at room temperature.
3/4 cup heavy cream
Melt butter and warm olive oil together in a large skillet over medium-high heat. Add onion to the skillet and cook for 2-3 minutes.
2 Tablespoons butter, 1 Tablespoon olive oil
Once the onion has begun to soften, stir in the zucchini or squash, asparagus, bell pepper, peas, and garlic. Cook for 3-4 minutes, until the veggies are tender-crisp. Use a large slotted spoon to remove them to a bowl and set aside.
Keep the pan over medium-high heat and add the wine, broth, lemon juice, and Italian seasoning. Bring the sauce to a simmer and let it bubble for 3-4 minutes.
1/2 cup dry white wine, 1/4 cup low-sodium chicken broth, 1 teaspoon fresh lemon juice, 1/4 teaspoon Italian seasoning
Stir in the cream. When the sauce is creamy and smooth, stir in the halved tomatoes and the Parmesan. Sample and season with salt and pepper to taste. (I usually start with 1/2 teaspoon salt and 6-8 turns of black pepper.) Cook for 1-2 minutes more, then reduce heat to medium-low and stir the veggies back in.
1 cup cherry tomatoes, 1/3 cup freshly-grated Parmesan cheese
Toss the drained pasta in with the veggies and sauce. Serve right away with more Parmesan and fresh basil as an optional garnish.
