Sheet-Pan Roasted Red Pepper Salmon with Vegetables

Sheet-pan dinners earn their keep on busy weeknights, and this combination of salmon and tender garden vegetables is a reliable example of why. As the oven heats to a steady 400°F, sweet red bell peppers and fresh zucchini roast right alongside the fillets, absorbing the olive oil and garlic seasoning as everything cooks in under twenty minutes.
Why this one works
- Everything cooks on a single sheet pan for quick prep and straightforward cleanup.
- Red bell peppers soften and develop sweet depth alongside the savory fish.
- Roasting at 400°F keeps the salmon moist and flaky without drying out.
- A simple pantry seasoning of garlic powder and sea salt enhances the natural ingredients.

What you’ll need
- 2 fillets (340g) salmon Check the flesh for pin bones and ensure the fillets are similar in thickness so they cook evenly.
- 1 cup (150g) red bell peppers, sliced Slice into uniform strips so they soften and pick up slight sweetness in the hot oven.
- 1 cup (150g) zucchini, chopped Cut into medium rounds or half-moons sturdy enough to hold their shape while roasting.
- 2 tablespoons (30ml) olive oil Evenly coats both the fish and cut produce to encourage gentle browning.
- 1 teaspoon (5g) garlic powder Provides consistent savory flavor that sticks neatly to the oiled surfaces.
- 1/2 teaspoon (3g) sea salt Seasons the salmon fillets and brings out the natural juices in the vegetables.

A few things worth knowing
- Distribute the sliced peppers and zucchini in a single layer around the fillets rather than piling them on top.
- Test the salmon by pressing lightly at the center; it is done when the flesh flakes cleanly under gentle pressure.
- Drizzle and season everything directly on the baking sheet to keep prep simple and minimize dishes.
Ways to make it your own
- Serve with fresh lemon wedges alongside the pan for a crisp squeeze over the hot fish.
- Sprinkle finely chopped flat-leaf parsley over the roasted vegetables right before plating.
Serving suggestions
Plate the warm salmon immediately next to a generous scoop of the roasted peppers and zucchini. The pan juices pair naturally with cooked grains like quinoa, steamed jasmine rice, or a slice of warm artisan bread to catch every drop.
Storage & reheating
Transfer any leftover salmon and vegetables into an airtight container and refrigerate promptly. Reheat gently over low heat in a skillet or warm oven until heated through to maintain the flaky texture of the fish.
