Mustard Baked Tilapia

Today's recipe I first posted on blog 12 years ago. Recently when I served baked tilapia with mustard for dinner, I thought about adding new pictures to the old recipe. Honestly, it's a nostalgic recipe.

Baked Tilapia

The aroma of fresh fish baking with mustard sauce reminded me of old blog days when I stood hours to take pictures of recipes. I was a newbie and had no idea of all photography gears that can do the job in minutes instead of hours.

What Do You Need to Make Baked Tilapia?

Here is what you need to make Baked Tilapia with Mustard Sauce:

  1. Tilapia Fillets
  2. Crème Fraiche
  3. Mustard - Dijon and wholegrain
  4. Capers
  5. Onion
  6. Lemon zest
  7. Salt and Pepper

Baked Tilapia Mustard Sauce Ingredients

That's it. Really all you need is: ingredients 2-7 are for Mustard Sauce and Tilapia. 

Mustard Sauce

For mustard sauce, I use French style clotted cream or crème fraiche. Crème Fraiche will not break when heated. This makes a creamy sauce which is never broken.

Two kinds of mustards - Dijon mustard and Wholegrain mustard adds double flavor of mustard and give perfect mustardy flavor to the sauce. I highly recommend using both. The flavor of onion is very subtle in the sauce. Along with capers, these two give sauce depth of flavor.

I have to say that while fish and lemon is match made in heaven, mustard works great with fish too. In-fact, I used a few tbsps of leftover sauce for dipping the vegetables I served on the side. So so good! Even if you don't want to bake the fish, you can try scrumptious mustard sauce with French fries or fresh steamed vegetables.

Tilapia

Tilapia is lean white fish. It is low in calories and bakes perfectly moist in 12-15 minutes. The best about baked tilapia is that you can use any tangy and bold flavor paste and it will make perfect flavorful tilapia.

Tilapia Fillets Ready to Bake in Oven

For instance, if you tried my recipe for Air Fryer Miso Salmon? The same Miso marinade goes great with tilapia fillets. Bake in the oven or even in the air fryer!

Note: Always remember to fully pat dry fish before baking. Moisture in fish will result in thin sauce. If using frozen fish, thaw fully and pat dry.

Baking Tilapia with Mustard Sauce

Once sauce is mixed and fillets are pat dried. Simply preheat the oven and get tilapia ready to bake.

Making Baked Tilapia

Spread a layer of sauce at the bottom of oven-proof dish. Layer fish in single layer on the top of mustard sauce. Spoon remaining sauce on the top covering fish completely. Fully covering fish in the sauce keeps fish moist as it bakes.

Tilapia Fillets with Mustard Sauce

Baking Tilapia Bake tilapia with sauce at 425 degree Fahrenheit for 12-15 minutes. Check in last 2-3 minutes. If fish flakes easily then it is ready.

Creamy Baked Tilapia Fillets

5 Ounce of crème fraiche makes good sauce to serve on the side with bread. Recipe also doubles easily.

When we are on vegetarian diet, I bake veggies such as cauliflower, broccoli in the same sauce. It makes an excellent vegetarian side dish. (hint hint)

Ingredients

Directions

  • Step for Recipe - Baked Tilapia with Mustard Sauce 1. Preheat the oven to 425 degrees F. In a bowl, combine the creme fraiche, both mustard - stone ground and dijon, minced red onion, capers, salt, black pepper, lemon zest. Mix well until salt is fully mixed in. Set aside.
  • Step for Recipe - Baked Tilapia with Mustard Sauce 2. Spoon 1/4 of the sauce on the bottom of a large ovenproof baking dish and spread evenly. Place tilapia fish fillets in the dish. Spoon the remaining sauce over the tilapia fillets, making sure the fish is completely covered.
  • Step for Recipe - Baked Tilapia with Mustard Sauce 3. Bake uncovered for 12 to 15 minutes, depending on the thickness of the fish. Once done take out and let rest for 5 minutes. Serve hot with the sauce from the pan spooned over the top. Enjoy with a slice of bread or rice and fresh salad.
Savita's Notes:
  1. Recipe doubles easily, you can always make it for 4 or 8, cooking time remains the same.
  2. Don't overcook the fish. Keep an eye in last few minutes. Tilapia will flake easily when it's done (check thickest part after first 10 minutes).
  3. Frozen Fish: If using frozen fish fillets, thaw fully before baking. Also wipe any trace of liquid with clean kitchen paper towel. Wet fish will result in watery sauce.
