Harissa-Lemon Sheet Pan Salmon with Carrots and Leeks

Spread the love

Over the summer, I pioneered what might be my favorite salmon marinade of all time—a bright, spicy harissa-lemon blend with a tough of maple syrup and a handful of chopped herbs. It was perfect for throwing fish on the grill and keeping around to drizzle on grain bowls.

Now that the weather is cooler, the easy grill situation has been replaced by ye ole sheet pan dinner. So I decided to give the harissa-lemon combo a try with one pan salmon and veggies. Well, my favorite marinade of all time may have just produced my favorite sheet pan salmon of all time. Yowzer.

The trick with sheet pan dinners is that you need to choose veggies that have roughly the same cooking time as your protein. This is tougher in fall months if you’re cooking fish or seafood, since most hardy root vegetables require a lot more time in the oven than 10 minutes.

So in this salmon sheet pan dinner we cheat a little, tossing the thinly sliced carrots with a little marinade and giving it a head start roasting away in the oven. After they become soft and caramelized, I toss in the leek, top the veggies with beautiful salmon fillets and douse everything with the remaining harissa-lemon mixture.

For those who aren’t familiar, harissa is a North African red pepper paste that’s ubiquitous in Tunisia and also widely used in Algeria and Morocco. It combines roasted bell peppers with hot peppers, cumin, coriander, garlic and other spices into a slightly sweet, earthy condiment that’s used to mix into soups, stews and couscous or to marinate meats.

After my trip to Morocco many years ago, I’ve kept some sort of harissa in the fridge as a hot sauce alternate and topping for tagines.

Since most commercial brands have garlic in the mix, it’s not low FODMAP, but you can easily swap it for a different hot sauce that is and omit the leeks to make this dish SIBO-friendly.

Harissa-Lemon Sheet Pan Salmon with Carrots and Leeks

This is truly the ultimate fall weeknight salmon sheet pan dinner. It’s easy to throw together, has lots of earthy vibes, and yet doesn’t leave you down for the count. The marinade is light, bright and slightly spicy thanks to the Moroccan red pepper paste harissa. To make this low-FODMAP simply omit the leeks and make sure your harissa doesn’t have garlic. If it does, swap any LF hot sauce. To make it Whole30 friendly, omit the maple syrup.
