Baked Fish with Lemon Cream Sauce
I have to be honest with you — I didn’t expect to fall in love with this recipe the way I did.
It started on a Tuesday evening. I had some white fish fillets thawing in the fridge and absolutely zero motivation to spend a lot of time in the kitchen. It had been one of those days, you know? The kind where the couch is calling your name louder than anything else.
But I also didn’t want to settle for a boring dinner — and that’s when I remembered this lemon cream fish recipe I’d bookmarked ages ago. One baking dish, a few pantry staples, and hardly any cleanup? I was sold.
What came out of the oven just 15 minutes later completely surprised me. The fish was melt-in-your-mouth tender, and the lemony cream sauce? Oh my goodness. Light, silky, with just the right hint of richness — I ended up dipping everything into it. Bread, broccoli, even my finger (don’t judge me).
So today I’m sharing it with you, because if there’s one recipe that can make you feel like a dinner genius with barely any effort, this is it.
Let’s make it together
Ingredients
- 4 white fish fillets (about 150–180g each), skinless and boneless
- Salt and pepper, to season
- 4 tablespoons (50g) unsalted butter
- 1/4 cup thickened or heavy cream
- 1–2 garlic cloves, minced
- 1 tablespoon Dijon mustard
- 1 1/2 tablespoons fresh lemon juice (plus more for serving if you love tang!)
- 1 1/2 tablespoons finely chopped eschallots (or shallots)
- Fresh parsley and lemon slices, for garnish
Instructions
- Preheat your oven to 200°C / 390°F.
You want it nice and hot so the sauce gets bubbly and the fish cooks quickly. - Place the fish fillets in a lightly greased baking dish.
Make sure they’re not crowded — they need a little space to cook evenly. Sprinkle both sides with salt and pepper. - In a small bowl, combine the butter, cream, garlic, mustard, lemon juice, and a pinch of salt and pepper.
Microwave in 30-second bursts until the butter melts and everything mixes into a smooth, creamy sauce. It smells so good already. - Sprinkle the chopped eschallots over the fish, then pour the warm sauce evenly over the fillets.
Don’t worry if it looks thin — it thickens slightly as it bakes, especially with the fish juices. - Bake uncovered for 10–12 minutes, or until the fish flakes easily with a fork.
Mine took exactly 11 minutes, and the kitchen smelled heavenly — buttery, garlicky, lemony… just yes. - Serve hot, spooning plenty of that luscious sauce over the top. Garnish with fresh parsley and a squeeze of lemon for a little zing.
Tips & Tricks
- Use fresh fish if possible — it releases less water and keeps the sauce creamier. But frozen is okay too! Just make sure you pat it dry really well after thawing.
- Don’t worry if the sauce looks thin at first. Once it mixes with the fish juices, it becomes silky and full of flavor. If it’s too watery, you can pop the dish back in the oven (without the fish) for a few minutes to thicken it up.
- Taste your sauce before baking. If you like more tang, add a tiny bit more lemon juice. Or if you’re a garlic lover like me, sneak in an extra clove.
Storage and Serving Suggestions
Storage:
Store any leftovers in an airtight container in the fridge for up to 2 days. Reheat gently on the stovetop or in the microwave — just don’t overdo it or the fish might dry out.
Serving ideas:
This sauce begs for something to soak it up. I love serving it with mashed potatoes, crusty bread, or fluffy rice. Add a simple salad or some steamed green beans, and you’ve got a cozy little meal that feels way fancier than it actually is.
FAQs
Can I use salmon instead of white fish?
I wouldn’t recommend it — salmon is quite fatty, and it can make the sauce split. Stick to leaner white fish like snapper, tilapia, or cod.
What if I don’t have cream?
You can substitute with evaporated milk in a pinch! It won’t be quite as rich, but still very tasty.
Can I add veggies to the pan?
Yes! Thinly sliced zucchini or asparagus spears work well — just make sure they cook quickly so they’re done when the fish is.
Final Thoughts
This recipe honestly surprised me — it’s so simple, but so satisfying. I’ve made it three times this month already (don’t tell my husband it’s the same dish, I just keep changing the sides).
I hope you love it as much as I did. It’s the kind of recipe that makes weeknight cooking feel like a little win — comforting, low-fuss, and absolutely delicious.

Ideal for white fish like Ling, Tilapia, Snapper, Barramundi, Basa, Hoki, Perch, or Flathead. Avoid salmon (too oily for the sauce) or very thin/delicate fillets like flounder.
