A semi-firm cheese that's nonetheless quite creamy, fontina melts into pure heaven. Combined with caramelized onions, fontina becomes a nutty, gooey, irresistible filling for chicken breasts.

Makes 4 servings

ACTIVE TIME: 35 minutes

TOTAL TIME: 35 minutes

EASE OF PREPARATION: Moderate

4 teaspoons extra-virgin olive oil, divided
1 1/2 cups thinly sliced red onion
2 teaspoons minced fresh rosemary, divided
1/8 teaspoon salt
Freshly ground pepper to taste
2/3 cup shredded fontina cheese, preferably aged
4 boneless, skinless chicken breasts (about 1 pound), trimmed of fat
1/2 cup white wine
1 cup reduced-sodium chicken broth
4 teaspoons all-purpose flour

1. Heat 2 teaspoons oil in a large nonstick skillet over medium-high heat. Add onion and 1 teaspoon rosemary; cook, stirring occasionally, until the onion is golden brown, 6 to 7 minutes. Season with salt and pepper. Let cool; stir in fontina.
2. Meanwhile, cut a horizontal slit along the thin, long edge of each chicken breast half, nearly through to the opposite side. Stuff each breast with 1/4 cup of the onion-cheese mixture.
3. Heat the remaining 2 teaspoons oil in the same skillet over medium-high heat. Add the chicken and cook until golden, about 5 minutes per side. Transfer to a plate and cover with foil to keep warm.
4. Add wine and the remaining 1 teaspoon rosemary to the pan. Cook over medium-high heat for 2 minutes. Whisk broth and flour in a bowl until smooth; add to the pan, reduce heat to low and whisk until the sauce thickens, about 1 minute. Return the chicken to the pan and coat with the sauce. Cook, covered, until the chicken is just cooked through, 2 to 4 minutes. Serve the chicken topped with the sauce.

TIP: Boneless, skinless chicken breasts, arguably the most versatile cut of chicken, are very low in fat, only 1 to 2 grams of fat per serving. Conveniently, one 4- to 5-ounce breast, tender removed, yields a perfect 3-ounce cooked portion. When preparing, trim any excess fat from the outer edge of the breast.

Chicken tenders, virtually fat-free, are a strip of rib meat typically found attached to the underside of
the chicken breast, but they can also be purchased separately. Four 1-ounce tenders will yield a 3-ounce cooked portion. Tenders are perfect for quick stir-fries, chicken satay or kid-friendly breaded "chicken fingers."

Good flavor, a great dish for a dinner party. Would suggest adding a bit more onions and fontina mix to allow a garnish on top when serving.

I prepared this for the first time, and definitely would make it again. The chicken was a big hit to my husband. All the ingredients were perfect.

This was fairly easy to make, elegant, and delicious. What more could you ask for? I made a little extra sauce to serve over my vegetables. Good as leftovers, too.

Quite a few steps if you're doing other things at the same time and wasn't all that flavorful.

I modified this somewhat (lemon juice instead of wine, added thyme and garlic and adjusted seasonings). It got rave reviews from my husband and (11-year old) kids.

I made this dish in a little under an hour! It was great! My husband loved it. I highly recommend trying this recipe.

I loved it; husband hated it. He likes Colby cheese, American cheese, and Swiss cheese--if it's paired with ham. Makes it a little boring in the cooking department.
