Salmon & Potato Bake With a Cheese & Mustard Sauce!

I remember the first time I made this dish. It was a particularly gloomy Sunday afternoon, and the fridge was looking rather bare. I had some leftover salmon from the night before, a bag of potatoes threatening to sprout, and a craving for something comforting and cheesy. What started as a culinary experiment born of necessity quickly became a family favorite. The combination of flaky salmon, tender potatoes, and that rich, tangy cheese sauce? Pure bliss.

Instructions

To begin, take the potatoes – adjust the quantity according to the number of people you’re serving, and remember to adapt the other ingredient amounts accordingly. Peel and rinse the potatoes.
Slice the potatoes into relatively thin slices and place them into a saucepan with lightly salted boiling water.
Parboil the potatoes for approximately 10 minutes, or until they are slightly soft. Check their tenderness by piercing a slice with a fork; it should offer a little resistance.
While the potatoes are parboiling, rinse the salmon fillets and then chop them into small chunks. This ensures even cooking and distributes the salmon flavor throughout the bake.
Once the potatoes have boiled sufficiently, drain them thoroughly.
Place the potato slices into an oven-proof dish, overlapping each other to create a layered base. This helps the potatoes cook evenly and prevents them from drying out.
On top of the potato base, add a generous amount of the salmon chunks, distributing them evenly across the potatoes. Season generously with salt and black pepper to taste. Don’t be shy with the seasoning; it will infuse the entire dish.
Now, prepare the cheese sauce. Add milk to a saucepan and bring it to a boil over medium heat. Keep a close watch to prevent it from boiling over.
Grate your strong cheddar cheese or parmesan cheese, setting it aside for later. A good quality, mature cheese will provide the best flavour.
While the milk heats, in a cup, mix cornflour with a small amount of cold milk to form a smooth paste. Ensure there are no lumps; this prevents a lumpy sauce.
Once the milk is boiling, slowly add the cornflour paste to the boiling milk, a little at a time, while continuously stirring to avoid lumps. This is crucial for a smooth, creamy sauce.
Repeat this action until the milk has thickened to a sauce-like consistency. The sauce should coat the back of a spoon.
When the sauce has thickened, add the minced garlic, finely chopped red chile, mustard, grated strong cheddar cheese (or parmesan), and chopped fresh parsley. Stir thoroughly until the cheese is melted and the sauce is nice and smooth.
Bring the sauce back to a gentle boil, then reduce the heat and simmer for 5-10 minutes more until all the flavors have infused together. Stir constantly to prevent burning or lumps from forming.
Season to taste with salt and pepper if needed. Remember, the cheese and mustard will contribute saltiness and tang, so taste before adding more.
Stir the sauce one last time and then pour it evenly over the potatoes and salmon chunks in the oven-proof dish. Ensure that everything is well coated with the cheese sauce.
Grate a generous amount of fresh parmesan cheese (or extra cheddar) over the top. This will create a delicious, golden-brown crust.
Place the dish in a pre-heated oven at approximately 190°C (375°F) for 1 ½ – 2 hours, or until fully cooked. The potatoes should be tender, the salmon cooked through, and the cheese topping golden and bubbly. Adjust cooking times and temperatures according to your oven.
If desired, you can crisp the top up further by briefly using the grill (broiler) during the last few minutes of cooking. Watch carefully to prevent burning!
Once cooked, remove the dish from the oven and garnish with a little more chopped fresh parsley for a pop of color and freshness.
Serve hot and enjoy!

Expert Tips & Tricks

Parboiling Potatoes: Don’t overcook the potatoes during the parboiling stage. They should be slightly firm, as they will continue to cook in the oven with the sauce.
Cheese Sauce Consistency: If the cheese sauce becomes too thick, add a little more milk to thin it out. If it’s too thin, mix a little more cornflour with cold milk and add it to the sauce, stirring constantly.
Spice Level: Adjust the amount of red chile to suit your preference. For a milder flavor, remove the seeds from the chile before chopping.
Make-Ahead Option: You can assemble the dish ahead of time and store it in the refrigerator until ready to bake. Add about 15-20 minutes to the cooking time if baking from cold.
Enhance the Salmon Flavor: Consider marinating the salmon in lemon juice, olive oil, and herbs for about 30 minutes before adding it to the dish. This will enhance its flavor and keep it moist during baking.

Serving & Storage Suggestions

Serve the Salmon & Potato Bake hot, straight from the oven. A side of steamed green vegetables, such as broccoli or green beans, complements the richness of the dish. You could also serve it with a crisp green salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through. Be sure to check the internal temperature of the salmon to ensure it’s thoroughly reheated. Freezing is not recommended as the texture of the potatoes and cheese sauce may change upon thawing.

FAQs (Frequently Asked Questions):

Q: Can I use pre-shredded cheese?
A: While pre-shredded cheese is convenient, freshly grated cheese melts more smoothly into the sauce.

Q: How can I prevent the potatoes from sticking to the bottom of the dish?
A: Grease the oven-proof dish well before adding the potatoes or use a non-stick dish.

Q: Can I use frozen salmon?
A: Yes, but make sure to thaw it completely and pat it dry before using it in the recipe.

Q: What if I don’t have strong mustard?
A: Dijon mustard or even a grainy mustard will work as a substitute, but the flavor will be slightly different.

Q: How do I know when the salmon is cooked through?
A: The salmon is cooked when it flakes easily with a fork and is no longer translucent in the center.
