What You Need to Make Keto Sheet Pan Salmon & Asparagus
- A large commercial-grade sheet pan – This is the #285239th time I’ve recommended these pans. Don’t have them yet? Do yourself a favor and buy them today.
- Parchment paper – Clean up is soooo much easier with parchment paper. Do NOT use wax paper.
- Small bowl – you’re going to mix all the ingredients in a small bowl. These stainless steel bowls are indestructible, dishwasher safe, and will last a lifetime.
- Salmon – You want the whole filet. Make sure it is deboned, but having the skin on is fine. There’s more info on salmon below.
- Asparagus – You need to start with about 1.5 pounds to feed a family of four.
- Dill – Fresh dill is preferable, but you can use 1 tsp dried dill if you don’t have fresh.
- Dijon Mustard – Go for the good stuff. The flavor makes all the difference!
- Garlic – A few cloves of fresh garlic chopped finely.
- Oil – I use olive oil but you can use your favorite oil.
- Lemons – I used a whole lemon for this dish. Half sliced thinly, the other half left whole.
How to Choose Salmon
There are so many kinds of salmon available today, and in so many different cuts. Navigating them can be difficult, but here’s a bit of a primer to help you find the perfect salmon.
- Choose wild-caught Pacific salmon if available, or if not, choose responsibly-farmed salmon.
- Pinker is not always better! Super-pink farmed salmon has been fed a diet rich in carotene, or worse, fed a chemical to make the flesh a darker color1.
- Look for a filet, the whole side of salmon, as opposed to cut up pieces. Cut portions will overcook in this dish.
- De-boned salmon is much easier to work with – ask the fish counter for de-boned salmon.
- It should already be de-scaled, but you can ask to make sure. If it’s not de-scaled, ask the fish counter to de-scale it.
- Skin on! Leaving the skin on helps the salmon stay moist.
- If you’re asking for a portion of a filet, ask for it from the “head” end. The tail end, the narrow part of the filet, is always tougher and drier.
- The kind of salmon doesn’t matter too much. Sockeye salmon is affordable and readily available.
- Buy it when it goes on sale, and freeze it (if it wasn’t previously frozen). I will often ask the fish counter for a still-frozen filet if it’s on sale and I know I’m going to freeze it.
- Final tip – ask for it to be packaged on ice. Salmon is notoriously perishable and will start to lose quality as soon as it is removed from refrigeration. Your fish counter might grumble at you, but they’ll pack it on shaved ice if you ask.
How Much Salmon Do You Need?
I like buying a 1.5-2 pound filet, that way I’ve got leftover salmon. But, for a reasonable portion, you’ll want about 4 ounces per person. So for four people, you’d need a pound of salmon.
How to Make KETO SHEET PAN SALMON & ASPARAGUS
- Snap and thoroughly wash the asparagus. Asparagus grows up from underground and can be very sandy in the brushy tips, so wash them well under cold, running water.
- Rinse the salmon, removing any loose scales.
- Mix the Dijon, oil, dill, and garlic in a small bowl.
- Lay the salmon on a parchment paper-lined sheet tray.
- Salt and pepper the salmon.
- Spread the dill mixture over the top of the salmon. Don’t worry about the skin side.
- Top with lemon slices.
- Arrange the asparagus beside the salmon and drizzle with oil and salt and pepper.
- Bake!
That’s it!
What to Serve With Keto Sheet Pan Salmon & Asparagus
Your favorite salad will go nicely with this dish, or add even more vegetable love to this meal with Beans with Bacon, or Braised Kale with Garlic. You don’t want big, competing flavors – let the salmon and asparagus be the star of the show! Keto Hollandaise Asparagus is another tasty option!
Is This Dish Freezer Friendly?
I’m known as the Freezer Queen, but to be honest, this dish won’t do well in the freezer. You can freeze it, but it is going to suffer.
Asparagus has a high water content so it’s going to lose its crunch and snap when you freeze and thaw it. And, with no sauce, there’s nothing to protect the salmon.
It’s best to enjoy this dish freshly-cooked, but it will keep fine in the fridge for 3-4 days.
