Follow these simple steps to create your Chicken Marengo With Mushrooms, Garlic, and Tomatoes:

1. Sear Chicken: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chicken thighs, skin-side down, and sear until golden brown, about 5-7 minutes. Flip and sear for an additional 5 minutes. Remove from the skillet and set aside.
2. Cook Onions and Garlic: In the same skillet, add the remaining olive oil, chopped onion, and minced garlic. Sauté until translucent and fragrant, about 3-4 minutes.
3. Add Mushrooms: Incorporate the sliced mushrooms into the skillet. Cook for another 5 minutes until they start to soften.
4. Deglaze with Wine: Pour in the dry white wine, scraping up any bits stuck to the bottom of the skillet. Let it simmer for 2-3 minutes.
5. Combine Ingredients: Add the diced tomatoes, chicken broth, thyme, salt, and pepper. Stir to combine all the ingredients well.
6. Return Chicken to Skillet: Place the seared chicken thighs back into the skillet. Bring the mixture to a gentle simmer.
7. Simmer: Cover and let it simmer for about 30 minutes, or until the chicken is fully cooked and tender.
8. Garnish: Once cooked, remove the skillet from heat and sprinkle fresh chopped parsley on top for added freshness.
9. Serve: Enjoy your Chicken Marengo while hot, paired with your choice of side.

These simple steps outline a rewarding recipe that yields incredible flavors and textures, making the effort worthwhile.
