Instructions
Heat the olive oil in a large skillet set over medium-high heat.
Pound the chicken breasts down to 1-inch thickness and season them with salt and pepper; add them to the heated oil and cook for 5 minutes, undisturbed.
Flip the chicken breasts over; add 1 tablespoon butter and continue to cook for 4 to 5 more minutes, or until cooked through. Internal temperature should register at 165˚F.
Remove chicken breasts from skillet and set aside; keep them covered.
Add remaining butter to the skillet. Stir in diced onions and cook for about 6 to 8 minutes, or until very soft. Stir frequently. If they start to burn, lower the heat.
Stir in the garlic and cook for 20 seconds. Stir in Italian seasoning, sugar, and balsamic vinegar; cook for 2 minutes.
Whisk in the chicken broth; continue to whisk and scrape up all the browned bits from the bottom of the skillet.
Increase the heat to High and cook for about 2 to 3 minutes, or until the liquid has reduced a bit.
Lower heat to medium and whisk in the cream; whisk continually for about 30 seconds so that the sauce doesn’t start to boil.
Let sauce come to a simmer; add the chicken breasts back to the skillet. Cook for 1 to 2 minutes, or just until chicken is heated through.
Remove from heat. Sauce will thicken as it stands.
