Lemon Butter Salmon with Roasted Potatoes & Broccoli
Some dinners just make you feel like you have your life together, even when the day has been anything but organized. Lemon Butter Salmon with Roasted Potatoes & Broccoli is one of those recipes for me.
I made this for my family last weekend after a particularly busy week. I wanted something comforting and flavorful, but I didn’t want a complicated recipe or a mountain of dishes afterward. I had salmon, potatoes, and broccoli on hand, so I decided to turn them into an easy roasted dinner.
The potatoes came out golden and crisp around the edges, the broccoli developed those delicious roasted bits, and the salmon stayed tender and flaky under a buttery lemon-garlic sauce. When I squeezed fresh lemon over everything at the table, the whole dish came together.
Everyone loved it, and I especially loved how little effort it took. It’s now one of my favorite recipes for a relaxed weekend dinner.

Ingredients
For the Salmon
4 salmon fillets, about 5–6 oz each
1 tablespoon olive oil
3 tablespoons unsalted butter, melted
3 garlic cloves, minced
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
½ teaspoon dried oregano
½ teaspoon paprika
½ teaspoon black pepper
¼ teaspoon salt
2 tablespoons fresh parsley, chopped
For the Vegetables
1 lb baby potatoes, halved
4 cups broccoli florets
2 tablespoons olive oil
½ teaspoon garlic powder
½ teaspoon dried oregano
¼ teaspoon black pepper
¼ teaspoon salt
For Serving
Lemon wedges
Fresh parsley
Optional red pepper flakes
Instructions
1. Prepare the Oven
Preheat your oven to 425°F (220°C).
Line a large sheet pan with parchment paper for easier cleanup.
2. Roast the Potatoes
Place the halved potatoes in a bowl.
Toss them with olive oil, garlic powder, oregano, black pepper, and salt.
Spread them on the sheet pan, cut-side down whenever possible.
Roast for 20 minutes.
3. Prepare the Lemon Butter
While the potatoes roast, combine the melted butter, minced garlic, lemon juice, lemon zest, oregano, paprika, black pepper, and salt.
Mix well.
4. Add the Broccoli
After 20 minutes, remove the pan from the oven.
Add the broccoli to the potatoes and toss lightly with the roasting juices.
Make some space in the center of the pan for the salmon.
5. Add the Salmon
Pat the salmon fillets dry with paper towels.
Brush each fillet with the lemon butter mixture.
Place the salmon skin-side down on the sheet pan.
Drizzle any remaining lemon butter over the top.
6. Finish Roasting
Return the pan to the oven and roast for approximately 10–14 minutes, depending on the thickness of the salmon.
The salmon should flake easily with a fork and reach 145°F (63°C) for a fully cooked result.
The broccoli should be tender with lightly browned edges and the potatoes should be golden and crisp.
7. Finish & Serve
Remove everything from the oven.
Squeeze fresh lemon juice over the salmon, potatoes, and broccoli.
Sprinkle with fresh parsley and a pinch of red pepper flakes if you enjoy a little heat.
Serve immediately.
My Tips for the Best Salmon
Don’t overcook the salmon.
Start checking it early because thicker and thinner fillets cook at different speeds.
Dry the salmon first.
Patting it dry helps the butter and seasonings stick better.
Give the potatoes a head start.
They need more time than salmon, so roasting them first keeps everything perfectly cooked.
Don’t overcrowd the pan.
Space between the vegetables helps them roast and caramelize instead of steaming.
Finish with fresh lemon.
The acidity balances the richness of the butter beautifully.
Diabetes-Conscious Version
This meal can fit nicely into a diabetes-conscious eating pattern.
Keep the potato portion moderate.
Increase the broccoli or add another non-starchy vegetable.
Choose salmon for its protein and healthy fats.
Use unsalted butter and control the added salt.
Avoid sweet sauces or glazes.
For a lower-carbohydrate version, replace half or all of the potatoes with cauliflower, zucchini, or additional broccoli.
Mediterranean-Inspired Twist
This recipe is especially easy to make Mediterranean-inspired.
Use:
Extra virgin olive oil
Fresh lemon
Garlic
Oregano
Parsley
A little dill
Add cherry tomatoes, Kalamata olives, or a sprinkle of feta to the roasted vegetables for even more Mediterranean flavor.
Easy Variations
Garlic Herb Salmon
Add fresh dill, thyme, and parsley to the lemon butter.
Spicy Lemon Salmon
Add red pepper flakes or a pinch of cayenne.
Parmesan Broccoli
Sprinkle Parmesan over the broccoli during the final 3 minutes of roasting.
Low-Carb Version
Replace the potatoes with cauliflower or zucchini.
Honey Lemon Salmon
For a sweeter version, add a small amount of honey to the lemon butter mixture.
What to Serve With It
This is already a complete meal, but you can add:
Greek salad
Cucumber tomato salad
Sautéed spinach
Roasted asparagus
Cauliflower rice
Fresh avocado salad
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for 2–3 days.
Reheat the salmon gently in a covered skillet or low oven so it doesn’t dry out.
The potatoes and broccoli can be reheated in an air fryer at 350°F (175°C) for several minutes to bring back their roasted texture.

Frequently Asked Questions
Can I use frozen salmon?
Yes. For the best texture, thaw it completely in the refrigerator and pat it dry before cooking.
Can I use other vegetables?
Absolutely. Asparagus, zucchini, green beans, Brussels sprouts, and cauliflower all work well.
Can I use sweet potatoes?
Yes. Sweet potatoes are delicious with the lemon-garlic salmon, although they still contribute carbohydrates.
How do I know when salmon is done?
The salmon should flake easily and reach 145°F (63°C) for a fully cooked fillet.
Can I make this without butter?
Yes. Replace the butter with extra virgin olive oil for a lighter Mediterranean-style version.
Is this a good diabetes-conscious dinner?
It can be. Salmon and broccoli are naturally low in carbohydrates, while potatoes provide most of the meal’s carbohydrates. Keeping the potato portion moderate and filling more of the plate with broccoli or another non-starchy vegetable can make the meal more balanced.
