We believe that cooking should be a source of joy, not a chore, and this recipe absolutely delivers on that principle every single time.

Gathering Your Ingredients

The real charm of this dish is found in its simplicity and the quality of the components. We have organised what you will need into two sections: the primary elements of the dish and the beautifully simple marinade that ties them all together.
For the Salmon and Vegetables
- Salmon Fillets: Four salmon fillets, each weighing around 170g (6oz). We suggest using skin-on fillets for added flavour and moisture, though skinless fillets will also work wonderfully.
- New Potatoes: 700g (1.5 lbs) of new potatoes, which should be scrubbed and then halved or quartered based on their size. Their waxy nature means they hold their shape perfectly during roasting.
- Asparagus: One large bunch (approx. 450g or 1 lb) of fresh asparagus, with the tough, woody ends removed.
- Olive Oil: Three tablespoons of extra virgin olive oil for the best possible flavour.
- Salt and Black Pepper: To your personal taste.
For the Lemon Herb Marinade
- Garlic: Three cloves, minced very finely.
- Fresh Dill: Two tablespoons of freshly chopped dill. If you’re not a fan of dill, fresh parsley is an excellent substitute.
- Lemon: One large lemon is needed; you’ll use the juice from one half and thinly slice the other.
- Olive Oil: Two extra tablespoons for the marinade.
- Dijon Mustard: One teaspoon (this is optional, but we find it adds a delightful tangy note).
Step-by-Step Instructions: Crafting the Perfect Baked Salmon with Potatoes and Asparagus
Just follow our straightforward steps to create this magnificent meal. The most important element is the timing—we ensure the potatoes get a head start so that every part of the dish is cooked to perfection at the same moment.
- Preheat and Prepare: To begin, set your oven to preheat to 200°C (400°F, Gas Mark 6). For an even speedier clean-up, line a large, rimmed baking sheet with baking parchment.
- Roast the Potatoes: Place the prepared new potatoes in a large bowl and toss them with 1 tablespoon of olive oil, a good pinch of salt, and a few twists of black pepper. Arrange them in an even, single layer on the prepared baking sheet. Roast for 20 minutes, by which time they should be starting to soften and turn golden at the edges.
- Prepare the Marinade: While the potatoes are having their initial roast, you can mix together the delicious dressing. In a small bowl, simply whisk the minced garlic, chopped dill, lemon juice, 2 tablespoons of olive oil, and the Dijon mustard (if you’re using it). Season with a little salt and pepper.
- Add the Asparagus: After the 20 minutes are up, carefully take the baking sheet out of the oven. Gently push the potatoes over to one side and add the trimmed asparagus to the empty side. Drizzle the asparagus with the last tablespoon of olive oil and give it a gentle toss to coat. Place the tray back in the oven for a further 5 minutes.
- Introduce the Salmon: Now it is time for our star ingredient. Remove the tray from the oven once more. Lay the salmon fillets skin-side down in the spaces between the vegetables. Spoon the prepared lemon and dill marinade evenly over each piece of fish. Finish by arranging the thin lemon slices on top of the salmon fillets.
- The Final Bake: Return the baking sheet to the oven for one last time, baking for a final 12-15 minutes. The precise cooking time will vary depending on the thickness of your salmon. The dish is ready when the salmon is opaque and flakes easily with a fork, the potatoes are tender and golden, and the asparagus is bright green and crisp-tender.
- Serve and Enjoy: Take the tray out of the oven and serve straight away. A fresh wedge of lemon on the side is always a lovely touch.
Expert Tips for a Flawless Finish
Having made this dish more times than we can count, we have learned a few valuable tricks over the years that help guarantee a perfect result every single time.
Choosing the Best Salmon
The quality of the salmon you use will make a significant difference to the final dish. Try to find fillets that have a vibrant colour and a firm feel. Both wild-caught and sustainably farmed salmon are fantastic options. We recommend leaving the skin on, as it not only protects the fish and keeps it wonderfully moist during cooking but also becomes deliciously crispy.
Getting Potatoes Perfectly Crispy
There are two key secrets to achieving wonderfully crispy roast potatoes. Firstly, ensure they are patted completely dry before you toss them in oil. Secondly, avoid overcrowding the baking tray. Giving them ample space allows the hot air to circulate freely, which roasts them to a crisp rather than steaming them.
Asparagus Perfection
To prevent your asparagus from becoming mushy and overcooked, try to select spears of a medium thickness, as very thin spears can cook too quickly. To prepare them, simply snap off the woody ends where they naturally break; this ensures you are left with only the most tender part of the stalk. They require only a brief spell in the oven to reach a perfect crisp-tender texture.
Variations and Substitutions
We consider this recipe a brilliant foundation, and we wholeheartedly encourage you to adapt it to your liking! Don’t hesitate to experiment with different vegetables and flavours to match your personal taste or to use up what you already have in the kitchen.
Veggie Swaps
This salmon and vegetable bake is remarkably versatile. If you don’t have any asparagus to hand, why not try one of these alternatives?
- Broccoli florets
- Green beans
- Bell peppers, chopped into chunks
- Cherry tomatoes (add these for the final 10 minutes of cooking time)
- Courgette chunks
Flavour Twists
You can easily alter the marinade for a completely new flavour profile. Consider swapping the dill for fresh rosemary or thyme to create a more robust, earthy taste. A pinch of red chilli flakes will introduce a gentle heat, while a splash of white wine in the marinade can add an extra layer of depth.

Frequently Asked Questions (FAQ)
We often receive questions about this particular recipe, so we have compiled the most common queries here to assist you.
Can I use frozen salmon?
Of course! You just need to make sure it has thawed completely before you begin cooking. The ideal method is to place it in the refrigerator overnight. Pat the fillets very dry with a paper towel before you add the marinade to help them roast beautifully.
How do I store and reheat leftovers?
Any leftovers can be stored in an airtight container in the fridge for up to two days. When it comes to reheating, we suggest gently warming the meal in an oven preheated to 140°C (275°F) for around 10-15 minutes, or until everything is heated through. This method helps to prevent the salmon from drying out, which can often happen in a microwave.
Is this meal healthy?
Yes, this is an exceptionally healthy meal. Salmon is full of high-quality protein and omega-3 fatty acids, which are fantastic for heart and brain health. As the NHS advises, incorporating oily fish into our diets offers significant benefits. The asparagus and potatoes contribute essential fibre, vitamins, and minerals, making this a genuinely well-rounded dish.
Why are my potatoes not crispy?
This issue is typically caused by one of three things: the oven temperature was not high enough, the potatoes were not sufficiently dry, or the baking tray was overcrowded. To achieve that perfect crispy finish, ensure your oven is fully preheated, pat the potatoes dry, and give them plenty of room to roast on the sheet.
