For a richer flavor, sauté the sliced mushrooms in a little butter or olive oil before adding them to the casserole dish. If you prefer a thicker sauce, you can add a tablespoon of cornstarch to the soup mixture before pouring it over the chicken. Fresh thyme sprigs added during baking will enhance the flavor profile. To elevate the presentation, garnish with fresh parsley or chives before serving. This dish can be prepared ahead of time and refrigerated for up to 24 hours before baking. Be sure to add about 15-20 minutes to the baking time if baking from cold.

Feb 26, 2025I used fresh caramelized onions instead of the soup mix, and it was amazing! A bit more work, but worth it.

Dec 31, 2024I found that 50 minutes was too long for my oven. Next time I will check the internal temperature of the chicken earlier.
