How to Make Keto Salmon with Asparagus

It doesn‘t take much time to get everything together for this dish. The most work that you will do will be preparing the garlic butter.

Let‘s get started.


  • salmon fillets
  • fresh asparagus
  • olive oil
  • butter
  • garlic
  • lemon juice (squeezed out of lemon)
  • garlic powder
  • onion powder
  • salt and black pepper
  • parsley

Some tips when buying salmon:

Remember a few things when shopping for salmon. The skin on or off is up to your preference.

Salmon should smell like fresh fish. The flesh should be bright pink and slightly firm.

Wild-caught Pacific salmon tends to have the most nutrients and is considered more healthy. Farmed salmon can be just as healthy as long as you do a little research.

Check the label to be sure that it‘s coming from an environmentally-friendly, sustainable farm.

Those that don‘t have that label could use antibiotics with their fish and waste to feed it.

Step-by-step by Instructions

Preheat the oven to 450F (230C). Line a baking tray with aluminum foil.

Now trim the asparagus. By trimming the asparagus, you are removing the woody, tough ends that are not edible.

You can do this with a knife or simply snapping it off. The end will snap off if you try and bend towards the bottom of the stem.

It will break right where you need it to remove the woody part.
