Before You Start: Tips & Ingredient Notes

• What’s the best type of salmon to use? I prefer skin-on, center-cut fillets for this recipe. The skin gets wonderfully crispy in the oven and adds fantastic texture. If you’re using frozen salmon, make sure it’s fully thawed and patted very dry with paper towels before seasoning.
• How should I cut the sweet potatoes? Aim for 1-inch (2.5 cm) cubes. If they’re too large, they won’t cook through in time; if they’re too small, they might burn. Uniformity is key here for even roasting.
• Can I use fresh herbs instead of dried? Absolutely! Fresh thyme or rosemary would be lovely. Just remember that fresh herbs are more potent, so you might want to use a bit less—about half the amount of dried—so they don’t overpower the delicate salmon.
• Why parchment paper? It’s not just for easy cleanup—it also prevents the sweet potatoes from sticking and burning on the pan, ensuring you get those perfect caramelized edges without any scorched bits.

How to Make Salmon and Sweet Potato

Storage & Freshness Guide

• Fridge: Store leftovers in an airtight container for up to 2 days.
• Freezer: Freeze cooked salmon and potatoes separately for up to 1 month.
• Reviving: Reheat in a 350°F oven until warm to maintain texture.

Serving Suggestions

Complementary Dishes

• A simple arugula salad — The peppery bite of arugula dressed with a light lemon vinaigrette cuts through the richness of the salmon beautifully.
• Steamed green beans or asparagus — Their bright, crisp texture provides a lovely contrast to the soft, roasted sweet potatoes.
• Quinoa or couscous — A fluffy bed of grains helps to soak up any delicious juices from the salmon and makes the meal even more filling.

Drinks

• A crisp Sauvignon Blanc — Its citrusy notes and high acidity are a fantastic partner for the oily, rich salmon and the sweet potatoes.
• Sparkling water with lemon — A non-alcoholic option that provides a clean, bubbly palate cleanser between bites of this flavorful dish.
• A light-bodied Pinot Noir — If you prefer red wine, a Pinot Noir has enough acidity and fruitiness to complement the meal without overpowering it.

Something Sweet

• Lemon sorbet — Its sharp, clean flavor is the perfect refreshing finish after a savory and satisfying meal.
• Dark chocolate with sea salt — Just a square or two of high-quality dark chocolate provides a bittersweet, elegant endnote.
• Poached pears — Gently spiced and served warm, they continue the theme of gentle sweetness in a light and delightful way.

Top Mistakes to Avoid

• Mistake: Not drying the salmon. If you skip patting the fillets dry, you’ll end up with steamed, pale salmon instead of one with a beautifully cooked, slightly crisp exterior. That moisture creates steam and prevents proper browning.
• Mistake: Crowding the pan. When you overcrowd the baking sheet, the sweet potatoes steam instead of roast. You’ll miss out on those delicious caramelized edges and fluffy interiors. If needed, use two pans.
• Mistake: Overcooking the salmon. Salmon continues to cook after it comes out of the oven, so it’s best to remove it when it’s just slightly underdone in the very center. Overcooked salmon becomes dry and chalky.
• Mistake: Skipping the lemon at the end. That final squeeze of fresh lemon juice isn’t just for show—it brightens all the flavors and cuts through the oiliness. It truly lifts the entire dish.

Expert Tips

• Tip: For extra-crispy salmon skin, start it skin-side down in a hot, oven-safe skillet on the stovetop for 2-3 minutes before transferring the entire skillet to the oven to finish cooking. This initial sear works wonders for texture.
• Tip: If your sweet potatoes are roasting too slowly, try par-cooking them. You can microwave the cubed potatoes for 3-4 minutes before tossing them in oil and spices. This guarantees a tender interior and a crispy exterior in the same cooking time as the salmon.
• Tip: Let the salmon come to room temperature for about 15 minutes before cooking. A cold fillet straight from the fridge will cook unevenly, potentially leaving you with an overcooked outside and a cold, undercooked center.
• Tip: Create a flavor paste by mixing the oil and spices with a teaspoon of Dijon mustard or a tablespoon of maple syrup. The mustard adds a tangy complexity, while the maple syrup enhances the natural sweetness of the potatoes and creates a gorgeous glaze.

FAQs

Can I use other types of fish?
Absolutely! This method works wonderfully with other firm-fleshed fish like cod, halibut, or sea bass. Just keep a close eye on the cooking time, as thinner fillets will cook much faster. The sweet potatoes will still need their 15-minute head start, but you might only need to cook a delicate fish like trout for 5-7 minutes after adding it to the pan.

How do I know when the salmon is perfectly cooked?
The best test is to gently press the top of the fillet with your finger or the back of a fork. It should feel firm but still have a little give, and the flesh should flake apart easily. If you have a thermometer, the internal temperature should read 125°F (52°C) for medium-rare or 135°F (57°C) for medium. Remember, it will continue to cook from residual heat after you take it out.

Can I prepare this ahead of time?
You can do some of the prep in advance to save time! The sweet potatoes can be peeled and cubed a day ahead—just store them submerged in water in the fridge to prevent browning. You can also mix the spice rub for the salmon. But for the best texture, I’d recommend assembling and roasting everything just before you plan to eat.

What can I use instead of smoked paprika?
If you don’t have smoked paprika, regular paprika will work, though you’ll lose that smoky depth. A great alternative is a pinch of chipotle powder for heat and smoke, or even a simple blend of onion powder and a touch of cumin for a different flavor profile. It’s a very forgiving recipe.

My sweet potatoes are still hard, but my salmon is done. What happened?
This usually means your potato cubes were cut too large, or your oven temperature was a bit low. To fix it, simply remove the cooked salmon to a plate and tent it with foil to keep warm, then return the potatoes to the oven for another 5-10 minutes until they’re tender. For next time, try cutting smaller cubes or giving the potatoes a 5-minute head start before adding the spices.
