Ingredients

Butter and Vegetables

  • 4-5 Tbsp. unsalted butter, divided
  • 8 oz. white mushrooms, thinly sliced
  • 6 oz. fresh baby spinach leaves

Protein and Grains

  • 1 lb. boneless, skinless chicken thighs, cut into 1 1/2-inch chunks
  • 1 cup dry quinoa

Liquids and Seasonings

  • 1 3/4 cup water
  • 1 dried bay leaf
  • Salt and pepper, to taste

Mustard Sauce

  • 3 Tbsp. Dijon mustard
  • 2 Tbsp. pure maple syrup
  • 1 Tbsp. fresh lemon juice

Garnish (Optional)

  • Fresh chopped parsley
  • Red pepper flakes

Instructions

  1. Sauté the mushrooms: In a 3-quart sauté pan or large skillet, heat 2-3 tablespoons of butter over medium heat until it shimmers. Add the sliced mushrooms and cook undisturbed for 5 minutes. Season with salt to taste, stir, and cook for another 4-5 minutes, stirring occasionally until the mushrooms are tender and browned. Remove mushrooms to a plate using a slotted spoon.
  2. Brown the chicken: Increase the heat to medium-high, add the remaining butter to the same pan. Once the butter shimmers, add the chicken chunks, season with salt and pepper, and cook, stirring occasionally, until lightly browned, about 7-10 minutes.
  3. Cook the quinoa: Stir in the dry quinoa, water, dried bay leaf, and additional salt and pepper to taste. Bring the mixture to a boil, then reduce heat to low and simmer partially covered for 15-17 minutes, or until the quinoa is tender and most of the liquid has been absorbed.
  4. Make the mustard sauce: While the quinoa cooks, whisk together the Dijon mustard, pure maple syrup, and fresh lemon juice in a small bowl. Set aside.
  5. Add spinach and combine: When the quinoa is tender, discard the bay leaf. Add the fresh spinach leaves to the pan, cover and cook for 1-2 minutes until wilted. Use tongs to toss the spinach with the quinoa and chicken evenly.
  6. Finish and serve: Stir in the sautéed mushrooms and the prepared mustard sauce until everything is well combined. Serve garnished with fresh chopped parsley and red pepper flakes if desired.

Notes

  • Use boneless, skinless chicken thighs for best flavor and tenderness.
  • If you prefer a spicier kick, increase the amount of red pepper flakes.
  • This recipe is easily doubled for larger groups by using a bigger skillet or pan.
  • Quinoa can be rinsed prior to cooking to reduce its natural bitterness, though it's optional here.
  • Fresh spinach can be substituted with baby kale or Swiss chard if desired.
