Trucha al ajillo is one of those Spanish dishes that proves how much flavor a handful of everyday ingredients can deliver. A whole portion trout is seasoned, dusted with flour and pan-fried until the skin turns golden and crisp, then finished with a warm garlic and parsley sauce loosened with a splash of apple cider vinegar.

It is quick, too. With two or three minutes per side in a hot pan, the fish cooks through while staying juicy, and the garlic majado comes together in the same skillet so nothing goes to waste. The vinegar cuts through the richness of the trout, keeping the whole plate bright and balanced.

How to Make Trucha al Ajillo Step by Step

1. Clean the trout of bones

Before you start, ask your fishmonger to clean 1 portion trout. For this recipe you need a trout without the central spine and cut butterfly style. To make sure no bones remain, use tweezers to pull out any that are left.

2. Season and flour it

Once the trout is free of bones, season it with salt and freshly ground black pepper. Then put 25 g of wheat flour on a plate and coat the trout in it.

3. Fry the trout skin side down

Heat 30 ml of olive oil in a wide skillet. When the oil is hot, fry the floured trout over high heat for 2 to 3 minutes, starting with the skin side. This keeps the fish from sticking to the pan and gives the trout skin a crisp finish.

4. Turn it over

Turn the trout over very carefully, lower the heat and cook for another 2 or 3 minutes over medium heat. Take the trout off the heat and move it to the plate you will serve it on, covered with another inverted plate to keep it warm.

5. Make a majado with garlic and parsley

Make a majado in a mortar with 2 garlic cloves and 1 bunch of parsley.

6. Add apple cider vinegar

Add 1 tablespoon of apple cider vinegar to the majado, stirring it in so the garlic and parsley paste loosens into a sauce.

7. Cook the sauce

Take the majado to the skillet where you fried the trout. Fry the garlic over medium heat and pour in a couple of tablespoons of water to create a sauce to go with the trout, cooking it for a couple of minutes until it comes together.

Tips for the Best Trucha al Ajillo

Oven alternative

Here we made the trout in a skillet. If you prefer to bake it, allow about 10 minutes at 180 °C with heat from above and below. For the first 8 minutes, bake the trout with just a little salt and pepper, then pour over the garlic majado, leave it a couple more minutes and it is ready. In a skillet the times are shorter: 2 or 3 minutes per side is enough.

Build the sauce in the same pan

The garlic majado is made separately, in the same skillet where the trout was fried. That way you use the flavor and the bits of flour left from frying to bind the garlic sauce. Finally, the sauce is poured over the trout so the fish takes on all the garlic flavor.

Balance the richness and get ahead

To lighten the richness of this fish, alongside the garlic we added apple cider vinegar to the majado, which can be swapped for lemon juice. Making and reducing the majado does not take long, but you can start the recipe with the majado and set it aside until you reduce it, so the trout does not go cold while you work. To accompany the trout we recommend roast potatoes, white rice or steamed vegetables.

30 Recipes I Keep Coming Back to in My Own Kitchen

Like a lot of home cooks, I like having a go-to lineup that covers cozy classics, well-known dishes from around the globe, and desserts that make everyone at the table happy.

Some nights I want something luxurious, and that's when I reach for this La Viña Molten Cheesecake recipe, this refined Original French Crème Brûlée recipe, or a truly indulgent Chocolate Mousse Cake recipe. And whenever a fruity, comforting sweet sounds right, this timeless French Tarte Tatin recipe is the one I make.

Mornings and lighter meals call for these airy Oatmeal and Banana Pancakes recipe, a filling Stuffed Sweet Potato recipe, or these bright Eggs Stuffed with Avocado and Salmon recipe. And for a gluten-free staple to keep in the pantry, this straightforward Gluten-Free Rice Flour recipe is one I rely on.

For small plates and Mediterranean cooking, I bounce between this punchy Basque Tuna with Tomato recipe, crispy Patatas Bravas Air Fryer recipe, velvety Tirokafteri Greek Dip Sauce recipe, and a cool Burrata Salad with Tomato and Pesto recipe. This crisp Italian Vitello Tonnato recipe also comes out when I want the meal to feel a bit more special.

Hearty midday meals and snug evening dinners? I'm always pointing people toward this warming Meatballs in Spanish Sauce recipe, traditional Meatballs in Almond Sauce recipe, deeply savory Italian Bolognese Sauce recipe, and silky Chicken Croquettes in Thermomix recipe. When I need something more substantial, out comes this oven-baked Greek Pastitsio Pie recipe, homey Potatoes and Squid Stew recipe, or the deeply soothing French Boeuf Bourguignon recipe.

Whenever street food or party food is on my mind, I'll whip up this succulent Homemade Chicken Doner Kebab recipe, crispy Salchipapas recipe, bold Mexican Pork Carnitas recipe, or these crunchy Korean Hobak Jeon recipe.

After years of cooking, testing, and tweaking in my own kitchen, I've come to believe the greatest dishes are built on straightforward methods, dependable technique, and serious flavor.

Every recipe gathered here is one I genuinely come back to time and time again—whether it's a fast solo meal or a spread I'm putting together for loved ones.

On the sweet side, the rich, velvety Orange Chocolate Mousse Recipe is a go-to when I want something that feels fancy yet comes together easily. Another dessert I adore is the caramelized Trdelnik Slavic Pastry Recipe, modeled on the well-known Central European chimney cake. If baking is your thing, knowing how to make syrup for better dessert texture helps a lot, and my Inverted Sugar Recipe walks through exactly how I do it at home.

When something light and uncomplicated is what I'm after, I'll go with the timeless Italian Caprese Salad Recipe or a spot-on Simple Poached Egg Recipe. For cozier, heartier fare, I'm quick to suggest the filling Meatball Sandwich Recipe, the luscious Russian Stroganoff Beef Recipe, and the speedy weeknight winner One Pot Pasta Recipe.

I'm also a big fan of sharing dishes with roots around the world, like the genuine Sorropotún de Bonito Fish Stew Recipe, crispy Chilean Pumpkin Sopaipillas Recipe, and the traditional Spanish Cochifrito Segovian Fried Pig Recipe.

The ones I make most are Air Fryer Pork Ribs Recipe, Air Fryer Chicken Thighs Recipe, Air Fryer Sweet Potatoes Recipe, Air Fryer Baked Potatoes Recipe, Air Fryer Peppers Recipe, Air Fryer Mixed Sandwich Recipe, Air Fryer Toasted Bread Recipe, and Air Fryer Hard-Boiled Eggs Recipe.

And for anyone steering clear of wheat, my cozy Gluten-Free Lasagna Recipe shows that a classic baked pasta can still be rich, cheesy, and deeply satisfying without any gluten.
