Forgotten chicken is one of those old-school dinners that deserves a serious comeback. Bone-in chicken thighs are seared until golden, then baked low and slow in a savory herb broth with caramelized onions, garlic, and cherry tomatoes until the meat is fall-off-the-bone tender. I make this when I want a dinner that feels special but mostly takes care of itself in the oven.
There is something about the smell of garlic and rosemary filling the kitchen while this dish bakes that just makes a house feel like home. That is the real magic of forgotten chicken. You do the work upfront with a good sear, then the oven does the rest. The sauce that builds in the pan from the chicken drippings, broth, and Dijon mustard is simple but deeply flavorful. Serve it over mashed potatoes or rice and you have a complete, satisfying dinner that tastes like it took much longer than it did.

Ingredients for Forgotten Chicken
I always use bone-in skin-on chicken thighs for this recipe because the skin crisps up beautifully during the sear and the bone adds real depth to the pan sauce as it bakes. Here is everything you need.
- 4 bone-in skin-on chicken thighs – I recommend thighs over breasts here for flavor and juiciness
- 2 tablespoons olive oil (extra virgin for richer flavor)
- 1 large yellow onion, thinly sliced
- 4 cloves garlic, minced – My preference is fresh minced garlic for the most vibrant aroma
- 1 cup chicken broth (low-sodium preferred so you can control the saltiness)
- 1 tablespoon Dijon mustard – In my experience, this adds a subtle tang that makes the sauce taste layered and complex
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- Salt and pepper, to taste
- 1 cup cherry tomatoes, halved (about 150g)
Step-by-Step Instructions
I recommend using a cast-iron or heavy oven-safe skillet for this recipe. In my experience, it holds heat evenly during the sear and transitions perfectly from stovetop to oven without any extra dishes.
Step 1: Preheat your oven to 375 degrees F (190 degrees C). Pat the chicken thighs completely dry with paper towels. This step is critical for getting a crispy skin. Season both sides generously with salt and pepper.
Step 2: Heat the olive oil in a large oven-safe skillet over medium-high heat until it shimmers. Place the chicken thighs skin-side down and sear for 5 to 7 minutes without moving them, until the skin is a deep golden brown. Flip and sear the other side for 3 minutes. Remove the chicken to a plate and set aside.
Step 3: In the same skillet, add the sliced onions to the leftover drippings. Cook over medium heat for 8 to 10 minutes, stirring occasionally, until soft and golden. Do not rush this step. Properly caramelized onions build the whole flavor base of the sauce.
Step 4: Add the minced garlic and cook for 30 seconds, stirring constantly, until fragrant. Pour in the chicken broth and scrape the bottom of the pan to release all the browned bits. Stir in the Dijon mustard, dried thyme, and dried rosemary.
Step 5: Return the chicken thighs to the skillet skin-side up. Scatter the halved cherry tomatoes around the chicken. Cover with a lid or aluminum foil and transfer to the oven.
Step 6: Bake for 25 to 30 minutes until the chicken reaches an internal temperature of 165 degrees F. Let rest for 5 minutes before serving. If you want a thicker sauce, place the skillet over medium heat on the stovetop for a few minutes, stirring, until it reduces slightly.
What to Serve with Forgotten Chicken
The rich savory pan sauce in this forgotten chicken dish pairs beautifully with sides that can soak it up or balance the bold herb and Dijon flavors.
Creamy Mashed Potatoes: Mashed potatoes are the most natural pairing for this dish. They absorb the herby pan sauce perfectly and create a complete, satisfying plate. This garlic herb chicken with mashed potatoes and glazed carrots is a great companion recipe that shares the same cozy comfort food spirit.
Fluffy White or Brown Rice: A simple bowl of rice works just as well as potatoes for soaking up the pan drippings and sauce. It is an easy, neutral base that lets the chicken take center stage.
Easy Balsamic Chicken and Veggie Orzo: For a lighter grain-based side that stays in the same herb-forward flavor zone, this easy balsamic chicken and veggie orzo adds color and a slightly tangy note that complements the Dijon mustard sauce.
Easy Chicken Breast and Green Beans: Simple roasted or steamed green beans add a fresh, slightly crisp contrast to the tender braised chicken. This easy chicken breast and green beans style prep makes a clean and quick side dish.
French Mustard Chicken: If you enjoy the Dijon mustard flavor in the pan sauce and want to explore a similar dish with a different technique, this French mustard chicken is a natural companion recipe worth trying next.
Baked Balsamic Chicken: For a simple oven-baked chicken variation that shares the same herb-roasted comfort food category, this baked balsamic chicken is a great recipe to bookmark alongside forgotten chicken for your weekly rotation.
How to Store and Reheat Forgotten Chicken
Store leftover forgotten chicken covered tightly in the refrigerator for up to 3 days. Keep the chicken and sauce together in the same airtight container so the meat stays moist. The sauce thickens overnight, which makes the leftovers even more flavorful the next day.
To reheat, I recommend placing the chicken in a covered skillet over medium-low heat with a splash of chicken broth to loosen the sauce. Warm for about 8 to 10 minutes until heated through. The microwave works for a quicker reheat in 60 to 90 second bursts, though the skin will soften.
Pro tip: this dish actually tastes better the next day once the herbs have had more time to settle into the sauce. It is one of those recipes that rewards patience and makes excellent leftovers for lunch.
FAQs
Can I use boneless chicken thighs or chicken breasts instead?
Yes. Boneless thighs work well but reduce the oven bake time to about 18 to 22 minutes. Chicken breasts can also be used but check them early since they cook faster and dry out more quickly than bone-in thighs.
What can I use instead of cherry tomatoes?
Diced regular tomatoes, canned diced tomatoes (drained well), or sliced bell peppers all work as substitutes. Bell peppers add a slightly sweeter flavor while still holding up well during baking.
Can I make this dish ahead of time?
Yes. You can fully cook the dish, let it cool, and refrigerate it for up to 24 hours. Reheat covered in the oven at 325 degrees F for about 20 minutes or until warmed through. The flavors deepen overnight, so make-ahead actually improves the dish.
