Pasta Carbonara Frittata

Position a rack in the center of the oven and heat the oven to 425°F.

Bring a 4-quart pot of salted water to a boil. Add the pasta and cook according to the package directions. Drain.

In a medium bowl, beat the eggs with a whisk, then whisk in the pecorino and cream.

Heat the oil in a 10-inch, ovenproof, nonstick skillet over medium heat. Add the bacon and cook until lightly browned, about 6 minutes. Add the onion and sage and cook until the onion is translucent and the bacon is crisp, about 5 minutes. Season with 1/4 tsp. salt and 1/4 tsp. pepper. Add the pasta and toss to distribute the ingredients evenly. Gently pour in the egg mixture. Transfer the pan to the oven and bake until a knife inserted in the center comes out clean, 12 to 15 minutes. Loosen the edges with a silicone spatula and slide the frittata onto a cutting board.

Whisk together the oil and vinegar in a small bowl. Put the radicchio, arugula, and shallot in a large bowl and toss with just enough of the vinaigrette to coat. Season with 1/2 tsp. sea salt and 1/2 tsp. pepper.

Sprinkle more black pepper on the frittata. Slice and serve with additional pecorino and the salad.
