Ingredients

Lemon Dill Mayo

  • 1/2 cup mayonnaise or unflavored greek yogurt
  • 1 tablespoon fresh dill finely chopped
  • Zest and juice of 1/2 a lemon
  • 1/2 tsp garlic powder
  • salt and pepper to taste

Slow-Roasted Salmon & Asparagus

  • 1 teaspoon ground cumin
  • 1/2 teaspoon ground coriander
  • 1/2 teaspoon ground fennel seeds
  • 1 teaspoon kosher salt
  • 1 pound salmon fillet (without bones or skin)
  • 2 tablespoons olive oil
  • 1/2 small red onion thinly sliced
  • 1 tablespoon red wine vinegar
  • 1 teaspoon honey
  • 1 bunch asparagus trimmed
  • 1 tsp olive oil
  • salt & pepper

Instructions

Lemon Dill Mayo

  • In a bowl, mix the mayonnaise, lemon zest and juice, garlic, salt, pepper, and fresh dill. Set aside.

Slow-Roasted Salmon and Asparagus

  • Preheat the oven to 275°F.
  • In a small bowl, combine the ground cumin, coriander, fennel seeds, and salt. Rub the spice mixture all over the salmon fillet. Let it sit at room temperature for 20-30 minutes to allow flavors to develop and take the refrigerator chill off the fish.
  • Thinly slice the red onion and toss in a bowl with red wine vinegar, olive oil, a pinch of salt, and honey.
  • Line a rimmed baking sheet with parchment paper. Place the seasoned salmon on the parchment paper and evenly distribute the onion mixture on top of the salmon.
  • Toss the asparagus with 1 tsp olive oil, salt and pepper. Arrange next to the salmon on a sheet pan.
  • Roast in the preheated oven for 25-35 minutes, or until the salmon flakes easily with a fork and reaches an internal temperature of 125°F. The onions should soften slightly but not completely. Allow to rest for 3-5 minutes

To Serve

  • Serve with your grain of choice (rice, quinoa, etc) or with a nice crusty bread and top with dollops of the Lemon Dill Mayo with more on the side to dip the asparagus in. Garnish with more fresh dill.
