👩🍳 How to Make Oven-Baked Chicken Marengo
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
If using a cast-iron skillet or Dutch oven, make sure it is suitable for stovetop and oven use.
🧂 Step 2: Season the Chicken
Pat the chicken thighs dry with paper towels.
Season both sides with salt and black pepper if desired.
Dry chicken skin browns more effectively and develops better flavor.
🔥 Step 3: Brown the Chicken
Heat the olive oil in a large oven-safe skillet over medium-high heat.
Place the chicken thighs skin-side down.
Cook for approximately 5–7 minutes, without moving them too much, until the skin is deeply golden.
Turn the chicken and cook for another 2–3 minutes.
Transfer the chicken to a plate.
It doesn’t need to be cooked through at this stage.
🧅 Step 4: Cook the Onion & Mushrooms
Reduce the heat to medium.
Add the sliced onion and mushrooms to the same skillet.
Cook for approximately 5 minutes, stirring occasionally, until the vegetables begin to soften.
The mushrooms will absorb some of the flavorful chicken juices left in the pan.
🍅 Step 5: Add the Tomatoes
Pour the crushed tomatoes into the skillet.
Stir gently, scraping up any browned bits from the bottom of the pan.
Those browned bits add tremendous flavor to the sauce.
Bring the sauce to a gentle simmer.
🍗 Step 6: Return the Chicken
Nestle the browned chicken thighs into the tomato sauce.
Keep the chicken skin mostly above the surface of the sauce so it has a chance to remain browned.
🔥 Step 7: Bake
Transfer the skillet to the preheated oven.
Bake uncovered for approximately 35–40 minutes, or until the chicken is thoroughly cooked and tender.
The thickest part of the chicken should reach at least 165°F (74°C).
For especially tender thighs, you can cook them a little longer.
✨ Step 8: Rest
Remove the skillet from the oven.
Allow the chicken to rest for 5 minutes before serving.
Taste the tomato sauce and adjust the seasoning if necessary.
🍽️ Step 9: Serve
Spoon plenty of the rich tomato and mushroom sauce onto each plate.
Place a chicken thigh on top.
For an extra rustic presentation, serve directly from the skillet at the table.
💡 My Best Tips for Perfect Chicken Marengo
Brown the Chicken First
Don’t skip this step.
Searing creates a golden crust and leaves flavorful browned bits in the skillet that enrich the tomato sauce.
Use Chicken Thighs
Bone-in thighs stay juicy during baking and are particularly forgiving if cooked a little longer.
Boneless thighs can also be used, but they’ll cook faster.
Keep the Skin Above the Sauce
If you’re using skin-on chicken, avoid completely submerging the skin.
This helps preserve some of its crispness.
Don’t Rush the Onion
Allowing the onion to soften before adding the tomatoes gives the sauce a sweeter, deeper flavor.
🌟 Delicious Variations
Chicken Breast Marengo
Use boneless, skinless chicken breasts.
Brown them briefly, then bake until the thickest portion reaches 165°F (74°C).
Because breast meat is leaner, avoid overcooking.
Garlic Chicken Marengo
Add minced garlic to the onion and mushroom mixture for a more aromatic sauce.
Olive & Herb Marengo
For a less strict five-ingredient version, add Kalamata olives and fresh parsley or thyme.
Creamy Chicken Marengo
Stir a small amount of heavy cream into the tomato sauce near the end of cooking for a richer variation.
Spicy Chicken Marengo
Add crushed red pepper flakes or a pinch of cayenne for a little heat.
🍚 What to Serve With It
The tomato sauce is delicious spooned over:
Mashed potatoes
Rice
Buttered noodles
Polenta
Crusty French bread
Sourdough
Cauliflower mash
For a lower-carb meal, serve with:
Cauliflower rice
Zucchini noodles
Roasted broccoli
Sautéed spinach
Green beans
A simple green salad also makes a fresh accompaniment.
🥡 Storage Instructions
Refrigerator
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 4 days.
Freezer
Freeze the chicken and sauce in airtight freezer-safe containers for up to 3 months.
Thaw overnight in the refrigerator before reheating.
Reheating
Reheat gently in a covered skillet over medium-low heat until hot.
Individual portions can also be microwaved in 60–90 second intervals.
Add a splash of water or broth if the tomato sauce has thickened too much.

❓ Frequently Asked Questions
What is Chicken Marengo?
Chicken Marengo is a classic French-inspired chicken dish traditionally prepared with chicken, tomatoes, and various savory additions. This simplified version focuses on five easy ingredients and oven-baking.
Can I use boneless chicken thighs?
Yes. Boneless thighs work very well and usually require less baking time.
Can I use canned diced tomatoes?
Yes. Crushed tomatoes create a smoother sauce, while diced tomatoes provide more texture.
Can I use fresh tomatoes?
Absolutely. Use ripe tomatoes that have been peeled and chopped, although canned tomatoes provide more consistent flavor year-round.
Can I make this recipe without mushrooms?
Yes. Simply omit them, although you’ll technically have fewer than five main ingredients.
Can I make it ahead of time?
Yes. The chicken and sauce can be prepared a day ahead and gently reheated before serving.
Can I make this in a slow cooker?
Yes, although you won’t get the same browned chicken skin. For the best flavor, brown the chicken and vegetables first, then transfer everything to the slow cooker.
How do I know the chicken is done?
Use an instant-read thermometer. The thickest portion should reach at least 165°F (74°C).
