How to make perfect Grilled Trout with Barley and Roast Vegetables
This dish has four components. That may sound like a lot, but it’s really not. For the best result I would suggest starting this recipe a few hours out from eating. This way you can have all the components ready. The only element that needs to be cooked right before serving is the Trout, the rest can be made in advance
The four elements needed to cook our Grilled Trout with Barley dish is the Trout (obviously!), Roasting the Vegetables, cooking the Barley, and finally making an amazing Dill Yoghurt sauce to serve

Begin by grilling the Vegetables
An easy first step in this dish is grilling the Vegetables. This has got to be one of the easiest methods for cooking Veggies, and it tastes the best. Roughly chop the Vegetables up and scatter them over a large sheet pan. You may even need two sheet pans depending on what Vegetables you’re using
We use a combination of Onions, Carrot, Celery, and Bell Pepper. Keep the Bell Pepper whole as it requires the skin and core to be peeled and removed once it’s cooked. Season the Vegetables generously with Olive Oil and Salt before roasting in the oven at 400F for about 35 – 40 minutes, turning halfway through
Once cooked, remove the Vegetables from the Oven and set them aside to cool, then chop into small pieces. For the Bell Pepper, allow it to cool then peel and discard the skin and core, then chop up and pair with the remaining Veggies

You can cook the Barley in advance, or cook while the Veggies are roasting
It’s up to you, but to save time you can get started on the Barley once the Vegetables are in the Oven. It’s very easy to make too, simply add it to a saucepan along with Chicken or Vegetable Broth (you can also just use water). Bring to a boil, then simmer, uncovered, for 30 minutes until the Barley is cooked and tender
You can replace the Barley with Farro if you like. They have similar flavor and textural components and cooking them requires the same method. Once the Barley / Farro is cooked, season it generously with Salt and taste before mixing in the chopped Vegetables
You can then simply leave the Barley in the saucepan while you finish preparing the dish. Just re-heat it over a medium heat while stirring for a few minutes just before serving and it’ll be perfect
A surefire way to guarantee crispy Trout skin every time
This technique is one we adopted for Salmon, but it works just as well with Trout and many other types of fish. The key to getting crispy fish skin is removing moisture from the skin before it’s cooked. In the case of Trout, there is a layer of fishy ‘gunk’ (that’s the best way I can describe it) that coats the outer skin
The gunk can be easily removed by simply scraping it off with a butter knife. You don’t want to scrape the skin too aggressively to damage it but simply scrape along the surface a bunch of times lightly. You will notice some grey gunk will begin to appear on the knife. Simply remove it and repeat it until the knife runs clean
I then like to Salt the skin generously and leave it out at room temperature for 30 minutes or so. The Salt will draw out more moisture from the skin which you can then easily pat away with a paper towel. Ensure the skin is dry before you begin cooking the Trout

Cooking the Trout
Add a touch of Neutral Oil to a frying pan set over medium heat. Once hot, place the Trout skin-side down onto the Oil. Press down on the flesh side of the Trout to ensure all of the skin maintains good contact with the pan. Season the flesh with Salt at this point
Then, simply fry it up for about 5 – 6 minutes until crispy and golden-brown. Flip the Trout over and fry it for a few more minutes on the flesh side and it’s cooked. I like to have my Trout slightly under, so it’ll be beautiful and pink and slightly opaque in the center
A Dill Yoghurt Sauce pairs perfectly over our Grilled with Barley and Roast Vegetables
This is a classic pairing with fish, and this dish is no exception. The vibrant flavors of Dill pair wonderfully with an easy Yoghurt Sauce mixed with Lemon Juice, Lemon Zest, and finely diced Garlic. Simply mix all these ingredients together in a bowl and then set aside

You can prepare the Yoghurt Sauce in advance and refrigerate it until ready to serve. It’s a super-versatile sauce as well, so any leftovers you have can be used in a variety of dishes. Even try spreading it over some crusty bread, it tastes great!
Plating
For quite a simple dish, our Grilled Trout with Barley ends up looking beautiful on the plate. The vibrant pops of color from the Trout and those wonderful Roast Vegetables makes for a tasty looking dish. To plate, add a few generous spoonful’s of the Barley mixture to a plate or bowl then top with a piece of Trout
Finish the dish by spooning over some of those wonderful Dill Yoghurt Sauce straight over the Trout. You can serve the dish with a few Lemon Wedges if you like and sprinkle the dish with some Flaky Sea Salt. Serve the Trout with some additional Yoghurt Sauce in a separate bowl and it’s ready!
