Asparagus, Ham, and Gruyere Frittata

Asparagus, Ham, and Gruyere Frittata
Recipe courtesy America’s Terst Kitchen

An ovensafe nonstick 12-inch skillet is a must for this recipe. Because broilers vary so much in intensity, watch the frittata carefully as it cooks.

Makes one 12-inch frittata, serving 6 to 8.

12 large eggs
3 tablespoons half-and-half
Table salt and ground black pepper
2 teaspoons olive oil
1/2 pound asparagus, trimmed of tough ends, spears cut on the bias into 1/4-inch pieces
1 medium shallot, minced (about 3 tablespoons)
4 ounces deli-style baked ham , 1/4-inch-thick, cut into 1/2-inch cubes about 3/4 cup)
3 ounces Gruyère cheese , cut into 1/4-inch cubes (about 3/4 cup)

  1. Adjust oven rack to upper-middle position, about 5 inches from heating element; heat broiler. Whisk eggs, half-and-half, 1/2 teaspoon salt, and 1/4 teaspoon pepper in medium bowl until well combined, about 30 seconds. Set eggs aside.

  2. Heat oil in 12-inch nonstick ovensafe skillet over medium heat until shimmering; add asparagus and cook, stirring occasionally, until lightly browned and almost tender, about 3 minutes. Add shallot and ham and cook until shallot softens slightly, about 2 minutes. Stir Gruyère into eggs; add egg mixture to skillet and cook, using spatula to stir and scrape bottom of skillet, until large curds form and spatula begins to leave wake but eggs are still very wet, about 2 minutes. Shake skillet to distribute eggs evenly; cook without stirring for 30 seconds to let bottom set.

  3. Slide skillet under broiler and broil until frittata has risen and surface is puffed and spotty brown, 3 to 4 minutes; when cut into with paring knife, eggs should be slightly wet and runny. Remove skillet from oven and let stand 5 minutes to finish cooking; using spatula, loosen frittata from skillet and slide onto platter or cutting board. Cut into wedges and serve.

STEP BY STEP: Three Steps to Cooking a Thick Frittata

  1. Start frittata on stovetop, stirring eggs as they set.
  2. When eggs form large curds but top is still wet, slide skillet under broiler.
  3. Once top browns, move skillet to cooling rack, where residual heat gently completes cooking center of frittata.
