The Secret to Perfect Roasting: Why 450°F is the Magic Number

Cooking salmon and asparagus at 450°F allows the salmon to cook thoroughly while staying moist and tender. This high heat also crisps the salmon’s edges without drying it out. At the same time, this temperature roasts the asparagus to a tender-crisp texture, preserving its freshness and bright flavor. It’s the perfect balance that makes this recipe foolproof and delicious every time. For more tips on roasting various items, check out The Ultimate Foolproof Roasted Vegetables Recipe.

A Quick Guide to Buying the Best Salmon

When selecting salmon, look for firm flesh that springs back when pressed and avoid any fishy smell. For this sheet pan recipe, either skin-on or skinless filets work well, though skin-on adds a bit more flavor and helps keep the fish intact. Wild-caught salmon tends to be leaner with a richer taste, while farmed salmon might be slightly fattier, which can affect cook time by a minute or so.

Ingredients for Salmon and Asparagus

Here’s exactly what you’ll need:

• 2 lbs salmon filet (cut into six – 6 oz portions)
• 2 lbs asparagus* (fibrous ends removed)
• Salt and black pepper (added to taste)
• 1 Tbsp olive oil
• 1 small lemon (sliced into rings for garnish)
• 6 Tbsp unsalted butter
• 2 Tbsp fresh lemon juice (from 1 small lemon)
• 2 garlic cloves (pressed or minced)
• 2 Tbsp fresh parsley (finely chopped)
• 1 tsp salt (we used sea salt)
• 1/4 tsp black pepper

How to Make Salmon and Asparagus: Step-by-Step

1. Preheat your oven to 450˚F with the rack in the top third. Line a large rimmed baking sheet with parchment paper trimmed to fit the pan edges.
2. Arrange salmon filets in a row down the center of the lined baking sheet. Place trimmed asparagus on both sides of the salmon. Drizzle asparagus lightly with olive oil and roll to coat evenly. Sprinkle salt and black pepper over both salmon and asparagus.
3. Prepare flavored butter by mashing together the unsalted butter, fresh lemon juice, minced garlic, chopped parsley, salt, and black pepper in a medium bowl using a fork. This takes a couple of minutes, but keeps mixing until smooth.
4. Spread butter over salmon and asparagus by spooning about 3/4 of the flavored butter on top of the salmon filets and spreading evenly. Dab the remaining butter onto the asparagus.
5. Top each salmon filet with a lemon slice for garnish. Bake uncovered at 450˚F for 10-12 minutes — thinner filets take 10 minutes, larger ones take 12. Set your oven to BROIL and cook another 2-3 minutes to give the salmon a golden finish.
6. Check doneness by ensuring the salmon flakes easily and reaches an internal temperature of 145˚F with an instant-read thermometer. The FDA recommends a minimum internal temperature of 145°F at the thickest part for safe consumption.

Tip: For best results, consider a heavy-duty baking sheet and a reliable instant-read thermometer.

Pro Tips for Perfect, Foolproof Salmon

• Know your salmon doneness by temperature: Medium-Rare at 125°F, Medium at 135°F, and Well-Done at 145°F.
• To prevent salmon skin sticking to parchment, ensure your paper is properly trimmed and dry before placing the fish.
• Avoid overcrowding your pan; give space between filets and asparagus for even roasting and crisp edges.
• Download the “Salmon Cooking Times & Temperature Chart” for easy visual reference and confidence in cooking.

Troubleshooting Common Issues

Help! My Salmon is Dry

Reduce cooking time slightly and check internal temperature earlier. Use the lemon garlic butter to keep moisture in the salmon.

Help! My Asparagus is Mushy

Make sure to remove fibrous ends and don’t crowd the pan. Roast at 450°F instead of a lower temperature to keep asparagus crisp-tender.

Help! My Pan Juices Burned

Trim parchment paper edges to avoid charring. If juices burn, place pan slightly lower in the oven or reduce broil time.

What to Serve with Salmon and Asparagus

• Fluffy quinoa makes a nutritious grain base to soak up buttery sauce.
• Roasted baby potatoes cooked separately complement the flavors perfectly.
• A simple side salad adds freshness and crunch.
• Crusty bread is great for mopping up leftover lemon garlic butter sauce.

Frequently Asked Questions

Can I use frozen salmon for this recipe?
Yes, but make sure to thaw completely and pat dry to avoid excess moisture, which can affect roasting.

How do I adjust cook time for very thick or thin asparagus?
Thicker asparagus may need 2-3 extra minutes in the oven; very thin asparagus cooks faster, so check earlier to prevent overcooking.

How do I scale this recipe for just two people?
Simply divide ingredient quantities by three and adjust cooking time slightly for smaller portions.

What’s the best way to store and reheat leftovers?
Store in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven or microwave to preserve moisture.
