Ingredients

For the Roasted Cauliflower

  • 1 large head of cauliflower, cut into bite-size florets
  • 2 tablespoons olive oil
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper

For the Seared Salmon

  • 4 pieces salmon fillet (about 6 oz. each)
  • 2 teaspoons olive oil
  • 2 garlic cloves, chopped
  • 1 tablespoon capers
  • 1/2 cup parsley leaves

Step-by-Step Directions

  1. Prepare the Cauliflower:
    Toss the cauliflower florets with olive oil, salt, and pepper. Arrange in a single layer on a large baking sheet. 
  2. Roast:
    Roast the cauliflower in a preheated oven at 450°F (232°C) for 20-25 minutes, shaking or turning the florets halfway through until they are tender and golden brown at the edges.
  3. Broil for Color:
    For deeper color and crisp, broil on high for 2-3 minutes at the end of roasting—but watch carefully to avoid burning!
  4. Prep and Cook Salmon:
    While the cauliflower roasts, season the salmon with a touch of olive oil, salt, and pepper. Heat a large skillet over medium-high heat. Add salmon, skin side down (if skin-on), and cook for 3-5 minutes, then flip.
  5. Add Aromatics:
    After flipping, add the chopped garlic and capers to the pan with the salmon. Continue to cook until salmon is opaque throughout and flakes easily (another 3-5 minutes).
  6. Combine and Serve:
    Toss the roasted cauliflower with the capers, garlic, and parsley. Serve alongside or beneath the seared salmon on each plate.

Expert Tips for Perfect Results

  • Even Cauliflower Size: Cut florets into similar sizes so they roast at the same rate.
  • Don’t Overcrowd the Pan: Spacing ensures caramelization instead of steaming.
  • Skin-On Salmon: If your salmon has skin and you enjoy it crispy, start cooking skin-side down. Press gently with a spatula to prevent curling.
  • Skip the Capers? If you don’t love capers, try sliced olives or simply stick with garlic and herbs.
  • Add a Splash of Lemon: A squeeze of fresh lemon juice or a little zest brightens the dish just before serving.

Why Salmon and Cauliflower Are a Perfect Pair

Salmon is rich in high-quality protein and Omega-3 fatty acids, promoting heart and brain health. Cauliflower is low in calories but high in fiber and micronutrients, making it a popular choice for healthy eaters. Together, these ingredients provide a balanced, satisfying meal with excellent nutrition and vibrant flavors.

How to Choose the Best Salmon

  • Look for vivid, moist flesh with no off-odors.
  • Wild-caught is generally leaner and more robust in flavor, while farm-raised is milder and fattier.
  • If buying skin-on fillets, the skin should be clean and slightly glossy.
  • Frozen fillets work well; just thaw overnight in the refrigerator for best texture.

Flavor Variations and Add-Ons

  • Sprinkle the roasted cauliflower with toasted nuts for extra crunch.
  • Add a side of whole grain farro or quinoa for more fiber and staying power.
  • Mix in other fresh herbs like dill, basil, or mint to the cauliflower for a fragrant twist.
  • For a Mediterranean touch, add feta cheese crumbles or a dollop of Greek yogurt on top.

What to Serve with Seared Salmon and Cauliflower

  • A crisp green salad with citrus vinaigrette
  • A side of wild rice or farro
  • Freshly baked whole grain bread
  • A simple lemony yogurt sauce

Storing and Reheating

  • Refrigerate: Store leftovers in airtight containers for up to 2 days.
  • Reheat: Warm gently in a skillet over low heat to maintain the salmon’s moisture. Microwave gently if needed, but be cautious to avoid drying out the fish.
  • Freezing: Salmon and cauliflower freeze well but are best enjoyed fresh for optimal texture.

Frequently Asked Questions (FAQs)

Can I use frozen cauliflower?

Yes, you can use frozen cauliflower. Roast it from frozen, adding a few extra minutes to the cook time. The texture will be a bit softer than fresh, but the flavors remain delicious.

What other fish can I substitute for salmon?

You can substitute arctic char, steelhead trout, or even firm white fish like halibut or cod. Adjust cooking time depending on the thickness of the fillet.

How do I know when the salmon is cooked through?

Salmon is done when it flakes easily with a fork and appears opaque throughout. For best results, cook to an internal temperature of 125–130°F, as it will continue to cook slightly after removal from the heat.

Are there low-carb options for the side?

Absolutely! Both roasted cauliflower and salmon are naturally low in carbs. For sides, stick with leafy salads, roasted bell peppers, or sautéed greens like spinach or kale.

Can I meal prep this recipe?

Yes. Prepare the full recipe, then store salmon and cauliflower in separate containers. Reheat gently for lunch or dinner within two days for best quality.

Chef’s Tips and Tricks

  • Pat salmon dry before seasoning to help develop a beautiful sear.
  • For crispier skin, start skin side down and avoid touching until ready to flip.
  • Use fresh parsley; it livens up the entire dish.
  • Add aromatics like rosemary or thyme to the roasting tray for more complexity.
