Baked Tilapia Fillets in Lemon Tarragon Sauce {Low Carb & Keto}

I just love having some super easy recipes in my keto arsenal.

This recipe for Baked Tilapia in Lemon Tarragon Sauce is one of those.

It’s easy to make and easy to clean up, so it’s perfect for busy weeknights.

But it’s also really delicious and fancy enough for date night.

It started out as me just throwing something together one night when I was totally drained from work and just wanted to eat.

Since then I’ve tweaked it a bit. And now it’s a sure fire home run every time I make it.

This recipe is for 2 people. Just add another tilapia fillet for any additional people and you’re good to go!

Baked Tilapia Fillets with Lemon Tarragon Sauce

  • 2 tilapia fillets
  • 1/2 med onion, thinly sliced
  • 1 lemon, cut in thin slices
  • 2 Tbsp lemon juice
  • 1 small can sliced mushrooms
  • 2 tsp olive oil
  • 2 tsp dried tarragon
  • salt & pepper to taste

Preheat your oven to 375°F.

Find a baking dish that the fillets fit into in a single layer.

Use the olive oil and spread it evenly over the bottom of the dish so the fish doesn’t stick.

Place the tilapia fillets in the dish skin side down. With a fork, poke several holes in the fillets and then pour 1 Tbsp on lemon juice evenly over each one.

Sprinkle with salt & pepper, and 1 tsp of dried tarragon over each fillet.

After 20 minutes, put the sliced lemons on top of the mushrooms and return to the oven for another 10 minutes.

The fish is done when it flakes easily with a fork. If your fillets are thick they may need a little more time.
