Instructions
Roast the potatoes: Preheat the oven to 425°F (220°C).Add 1 pound potatoes cut into 1-inch chunks. Toss with 1 tablespoon olive oil, ½ teaspoon salt, and ¼ teaspoon blackpepper. Spread them out in a single layer.Bake for 15 minutes.
Make the sauce: In a small bowl, whisk together 3 tablespoons extra virgin olive oil, 3 tablespoons lemon juice, 2 tablespoons Dijon mustard, 2 tablespoons honey, 3 cloves garlic, ½ teaspoon dried oregano, ½ teaspoon salt, and black pepper.
Add the salmon and green beans: Remove the pan from the oven. Push the potatoes to one side of the pan. Add 12 ounces green beans and 4 salmon fillets.Toss the green beans with a few spoonfuls of the sauce. Spoon the remaining sauce generously over the salmon.
Finish and serve: Bake for 12 to 18 minutes, depending on the thickness of the salmon, until it flakes easily with a fork and reaches 145°F (63°C) in the thickest part.If the green beans need a few more minutes, transfer the salmon to a plate and return the vegetables to the oven until tender.Divide the salmon and vegetables among plates. Spoon any extra honey mustard sauce from the pan over the salmon and vegetables before serving with lemon wedges.
Notes
Substitutions
Salmon → Steelhead trout, cod, halibut, or another firm fish. Frozen salmon works too; thaw overnight in the refrigerator first.
Potatoes → Yukon Gold potatoes, red potatoes, baby potatoes, or sweet potatoes.
Green beans → Broccoli florets, asparagus, zucchini chunks, Brussels sprouts, or sugar snap peas.
Olive oil → Avocado oil or another neutral cooking oil.
Dijon mustard → Whole grain mustard or spicy brown mustard.
Honey → Maple syrup or agave nectar. Or leave it out and add a little extra olive oil.
Lemon juice → Lime juice or a splash of white wine vinegar.
Garlic → Garlic-infused olive oil for garlic-intolerant people, or simply skip it.
Dried oregano → Italian seasoning, thyme, dill, or parsley.
Tips
Cut evenly: Similar-size potato chunks cook more evenly.
Pat the salmon dry: The sauce sticks better and the salmon browns more nicely.
Give it space: Don't overcrowd the pan. The green beans can overlap a little.
Check the temperature: Salmon is done at 145°F (63°C) in the thickest part.
Use the pan sauce: Spoon the flavorful juices over everything before serving.
Frozen green beans work: Add them straight from the freezer; they may need a few extra minutes.
Watch thick fillets: Thick salmon pieces can take longer to cook than thinner ones.
Finish with lemon: A squeeze of fresh lemon brightens the whole dish.
Store leftovers: Refrigerate for up to 2 days for an easy next-day lunch.
