Healthy Dinner Recipe
This sheet-pan Lemon Garlic Salmon with Roasted Sweet Potatoes and Asparagus is a healthy dinner recipe that’s quick, colorful, and packed with protein, fiber, and bright, fresh flavors.
I’ve been perfecting this dish ever since my daughter Emily begged for “that yummy fish night” last spring. What makes it unique is how easy cooking meets balanced diet—just one tray, minimal chopping, and a handful of pantry staples. Salmon delivers heart-healthy Omega-3s (USDA reports a 4-oz fillet has about 23 g protein and 2 g Omega-3 fats), while sweet potatoes add fiber and vitamin A. Toss in crisp asparagus, and you’ve got a nutritious meal that feels special enough for guests yet simple enough for a busy weeknight. You know what? I sometimes serve it alongside a crisp green salad or my quick lemon-parsley quinoa.

Ingredients for This Healthy Dinner Recipe
• 4 wild-caught salmon fillets (4 oz each; try Wild Planet Brand)
• 2 medium sweet potatoes (about 1 lb total), cut into ½″ wedges
• 1 lb asparagus spears, tough ends trimmed (sub: green beans)
• 2 Tbsp extra-virgin olive oil (California Olive Ranch recommended)
• 3 cloves garlic, minced (or ¾ tsp garlic powder)
• Zest and juice of 1 large lemon (Meyer lemon adds sweetness)
• 1 tsp dried thyme (or 1 Tbsp fresh, finely chopped)
• ½ tsp smoked paprika (optional for warmth)
• Sea salt and freshly ground black pepper, to taste
• Fresh parsley, chopped (for garnish)
• Lemon wedges, for serving
Tips:
– Choose firm, even-colored sweet potatoes—avoid ones with greenish patches.
– Pat salmon fillets dry with a paper towel so the marinade really clings.
– Break asparagus with your hands; it snaps at the natural breaking point.
– Pre-mince garlic and store in the fridge up to 2 days—saves time.
Directions
-
Preheat and Prep
Preheat oven to 425 °F (218 °C). Line a large, rimmed baking sheet with parchment paper or a Silpat. While the oven warms up, wash and chop your veggies—sweet potatoes first, then asparagus. -
Season the Sweet Potatoes
In a medium bowl, toss sweet potato wedges with 1 Tbsp olive oil, ¼ tsp salt, ¼ tsp pepper, and half the smoked paprika. Spread them out on one side of the pan so they roast, not steam. -
Roast Sweet Potatoes Alone
Slide the pan into the oven for 10 minutes. This head start ensures crisp edges. (You’ll thank me later when they’re golden.) -
Marinate the Salmon
While the potatoes roast, whisk remaining olive oil, garlic, lemon zest, juice, thyme, and a pinch of salt and pepper in a small bowl. Coat each salmon fillet generously; let them rest at room temperature for 5 minutes. -
Add Salmon and Asparagus
Remove the pan. Nestle salmon fillets skin-side down on the empty side. Arrange asparagus spears beside or between fillets—avoid overlap. Drizzle any leftover marinade over veggies. -
Final Roast
Return to oven for 12–15 minutes, until salmon flakes easily (internal temp ~145 °F) and asparagus is tender-crisp. If you like extra char, broil for 1–2 minutes on high, watching closely. -
Garnish and Serve
Transfer to plates or a large serving platter. Sprinkle chopped parsley and a squeeze of fresh lemon juice over everything. Serve immediately with extra lemon wedges.
Chef’s Tip: If you prefer your sweet potatoes softer, lower oven to 400 °F after the initial roast and give everything an extra 3–5 minutes.
Servings & Timing
Yield: Serves 4
Prep Time: 15 minutes
Chill/Rest Time: Optional 5–15 minutes for marinade
Cook Time: 22–25 minutes (including initial sweet potato roast)
Total Time: About 35 minutes (plus optional marinade)
Variations
• Swap salmon for boneless chicken thighs—adjust cooking to 20 minutes.
• Vegan twist: replace fish with firm tofu slabs, marinated the same way.
• Southwestern flair: use cumin and chili powder instead of thyme.
• Mediterranean spin: scatter halved cherry tomatoes and olives before roasting.
• Add chickpeas for extra fiber—toss a drained can with sweet potatoes step 2.
• Sprinkle crumbled feta and fresh oregano just before serving.
Storage & Reheating
Store cooled leftovers in an airtight container in the fridge for up to 3 days. To freeze: separate salmon fillets and veggies in freezer-safe bags; keep up to 2 months. Thaw overnight in the fridge. Reheat in a 350 °F oven for 10 minutes or microwave on medium power for 1–2 minutes—just until warm, so fish stays moist. Make-ahead: prep veggies and marinade up to a day ahead; roast day-of for maximum crispness.
Notes
– I learned the hard way that overcrowding the pan yields soggy veggies—give each piece breathing room.
– If your salmon is extra thick, tent loosely with foil after cooking so it rests and finishes gently.
– A sprinkle of red pepper flakes wakes up muted flavors; add sparingly.
– For even faster cleanup, use aluminum foil instead of parchment (just spray lightly).
– Taste as you go—seasoning levels can vary by brand of olive oil or lemon size.
FAQs
Q: Can I use frozen salmon fillets?
A: Yes—fully thaw and pat dry before marinating to avoid extra moisture.
Q: What if I don’t have fresh asparagus?
A: Swap with green beans, broccoli florets, or zucchini slices—adjust cook time based on thickness.
Q: Is this recipe gluten-free?
A: Absolutely—it contains no wheat or gluten ingredients unless you add a side that does.
Q: How do I know when salmon is done?
A: It should flake easily with a fork and reach 145 °F internal temp. If you don’t have a thermometer, look for opaque flesh.
Q: Can I double the recipe for a crowd?
A: Yes—just spread across two pans so heat circulates evenly.
Q: Will leftovers reheat well?
A: They do—just don’t overheat, or the salmon can dry out. Consider reheating veggies separately for best texture.
Q: Can I swap sweet potatoes for regular potatoes?
A: You can, but sweet potatoes offer more fiber and vitamin A; white potatoes may need a longer roast.
Q: What sides go best with this?
A: A leafy green salad, quinoa pilaf, or even warm whole-grain rolls complement the flavors nicely.
