Mustard-Baked Chicken

This mustard-baked chicken is a wonderfully simple way to elevate humble chicken legs into a deeply flavoured, aromatic main course. By marinating the meat in a punchy mixture of whole-grain mustard, garlic, and toasted fennel seeds, you achieve a sophisticated depth of flavour with very little effort. The apple cider vinegar cuts through the richness of the olive oil, helping to create a beautifully crisp, golden skin during roasting.

As a diabetes-friendly recipe, this dish is naturally low in carbohydrates and high in protein, making it an excellent choice for a balanced evening meal. It is incredibly versatile and pairs perfectly with a fresh garden salad or a side of steamed seasonal vegetables. This reliable traybake is sure to become a favourite for busy weeknights when you want a nutritious, home-cooked meal that doesn't compromise on taste.

Ingredients for Mustard-Baked Chicken

  • 2 whole pasture-raised chicken legs, thighs, and drumsticks separated

  • 60ml extra-virgin olive oil

  • 2 tablespoons whole-grain mustard

  • 4 garlic cloves

  • 1 teaspoon fennel seeds

  • 1 teaspoon apple cider vinegar

  • 2 teaspoons sea salt

How to make Mustard-Baked Chicken

Preheat the oven to 400˚F.

In a large bowl, toss all the ingredients together and allow the chicken to marinate for 15 minutes in the refrigerator. Transfer the chicken to a baking dish and spoon any excess marinade over it. Bake for 20 to 30 minutes, or until a nice brown crust forms on top of the meat. Serve warm.
