10-Minute Grouper Fish Tacos — Fast, fresh, and healthy! An easy fish taco recipe everyone loves! Lemony, buttery fish with a honey mustard-lemon sauce on top! Perfect for busy nights because they’re so quick!!
Easiest Fish Tacos with Grouper
I made this recipe with no intention of blogging about it. Just a family dinner that was going to be eaten and likely forgotten about.
Until my daughter told me it was the best dinner of her life.
Sometimes I think she’s exaggerating and next month there may be a new best-of-my-life, but for this month I’ll take the compliment and share the recipe.
Fish and lemon go hand-in-hand and the grouper is simply prepared by searing it in butter, lemon juice, salt and pepper. When fish is fresh and tasty I think it’s a disservice to do too much to it and mask the natural flavors. Simple, clean, and easy is the way to go and it stays healthier that way.
I made the fish while on vacation and it’s a one-skillet recipe that’s ready in 10 minutes and there are planned leftovers.
Ingredients for Grouper Tacos
To make these quick and easy grouper fish tacos, you’ll need the following:
- Grouper filets
- Lemon juice
- Shredded cheese
- Grainy Dijon mustard
- Salt and pepper
What Is Grouper?
If you’ve never tried grouper, it’s a firm, extra lean, flaky, white fish that’s mild in flavor. It’s a non-fishy-tasting fish, perfect for kids or those who are picky about fish.
How to Make Grouper Tacos
It doesn’t get much easier than this 10-minute taco dinner! Here’s an overview of how the tacos come together:
- To a large skillet, add the butter and melt.
- Dredge grouper fish through flour, coating both sides.
- Add fish to skillet, season with salt and pepper, and cook until nicely seared and lightly golden browned. Flip fish, season with salt and pepper, squeeze the lemon over the fish and cook on second side until lightly golden browned on both sides and cooked through.
- Lightly warm each tortilla momentarily on a dry skillet over medium-high heat before adding lettuce, sliced fish, sprinkling with tomatoes, and cheese; set aside while you make the sauce.
- To a small bowl, add the mustard, honey, lemon juice, salt, pepper, and whisk to combine. Drizzle sauce over tacos and serve immediately.
Ways to Serve the Grouper Fish
I served the grouper with rice and a simple salad the first night.
The second night I sliced it for fish tacos complete with lettuce, tomatoes, cheese, and a whisk-together honey mustard-lemon sauce. Lots of very clean plate club members, which made me happy!

- Add fish to skillet, season with salt and pepper, and cook for about 3 to 4 minutes on first side, or until nicely seared and lightly golden browned.
- Flip fish, season with salt and pepper, squeeze the lemon over the fish (use caution because the lemon juice will bubble up when it hits the hot skillet) and cook for about 2 to 3 minutes on second side, or until fish is lightly golden browned on both sides and cooked through. Serve immediately if desired.
- To make the fish tacos, lightly warm each taco shell momentarily on a dry skillet over medium-high heat before adding lettuce, sliced fish, sprinkling with tomatoes, and cheese; set aside while you make the sauce.

I have not try grouper fish yet. Your recipe is fine and it looks stunning. Hope I can make your recipe perfect with grouper. Let’s try this weekend.
I have to be honest; I usually come to your blog for your dessert recipes. They are all so delicious, but when I saw this recipe come into my inbox I had to try it.
Our family loved it! It was very kid friendly and delicious!!
Thanks for trying the recipe and I’m glad it came out great for you! This isn’t a recipe that gets a lot of comments on it from people who’ve made it so I really appreciate you coming back to let me know. And of course for following along with my dessert recipes too :)
Anytime my family raves over a meal, it’s definitely “blog worthy” as my family would say.
These sound like cheesey veg heaven! Love this dinner idea, might have to make a trip to the grocery store for tonight!!!
Living along the gulf of mexico, grouper is always within our reach. I’ve just never heard of it this way, but it looks and sounds amazing! Don’t you love it when your kids compliment like that?! It’s the best! :-)
That’s awesome that you have access to awesome fish based on your location!
That for sure is a great compliment from your daughter! The fish looks perfectly cooked! :-)
I feel like that always happens to us on vacation.. maybe it’s the change of scenery that gets the creative juices flowing?! Either way, these fish tacos look amazing.. pinned! :)
Don’t you just love it when easy recipes that you just throw together for a family dinner turn into something better than what you expected? We love easy fish recipes, as we try to eat fish at least once a week, so quick and easy ideas are always welcomed in our house, especially when they are that good looking!
These look so good!! I love fish tacos, abd a 10 minute, 1 pan meal? Yes, please!!
If only Jordan said that to me about dinners!!! Unless it’s takeout I’ve never heard those words, lol. I need to remember my Costco fish in the freezer more often, it’s the perfect quick dinner!
Funny because I had written this post/made the recipe awhile back and I had to keep juggling my posting schedule and when I read what I wrote about ‘best dinner ever’ it’s good I wrote that when I did because I never would have remembered it otherwise!
Thanks for pinning, too :)
These look incredible! I love fish tacos!
Oh, man. For someone who normally isn’t the hugest fish fan, you’ve totally convinced me with these gorgeous tacos! I can usually be persuaded by anything with the words “10-minute” and taco in the same sentence. ;) Gotta try these for dinner asap!
Glad that even as a fish lover you’re persuaded :)
My hubs and I fell in LOVE with Grouper when we first had it in the Bahamas awhile back, and we actually haven’t had it since. This recipe totally reminded me that I need to make it again, especially when it only takes 10 mins! Pinned!
Grouper is a favorite of mine. I love going to the beach and getting a fried grouper sandwich by the water. Nothing says summer more than that!
And putting it into fish tacos is just as delicious. Great recipe!
There’s nothing like a beach day summertime sandwich at the water, is there!
These just scream fresh summer food! The honey mustard sauce sounds good too for something a little different than the usual taco flavors. I love grouper (and snapper) but it’s a little hard to find here so it’s always something I get frequently whenever I’m in the Caribbean. Nothing like fresh caught!
Ha! I may have made this dinner while in the Caribbean :) I went to the fish counter and was going to buy salmon because it’s one of my daughter’s usual faves but after seeing the price, the grouper was about 1/4th the cost and she ended up loving it just as much!
