Slow-Roasted Salmon with Walnut-Olive Vinaigrette

This dish popped into my feed under the heading, “One of Food & Wine Magazine’s Most Popular Recipes of 2021.” The recipe tab sat open on my desktop for two weeks until “Aunt Lissa” was coming into town and I had the perfect occasion to prepare Slow-Roasted Salmon with Walnut-Olive Vinaigrette. Now, any of you planning Passover Seder or Easter dinner have the perfect main to serve!

I tend to cook my salmon “quick and high,” which translates to a short amount of time under high heat, whether it be via a conventional oven, broiler, grill, toaster oven or even air fryer (my newest salmon-cooking discovery). But this recipe has you cooking the fish, low and slow. The low heat paired with a basting of paprika-oil keeps the salmon super moist and the result is a perfectly cooked piece of fish. The Walnut-Olive Vinaigrette is more like a chunky tapenade and while it is super easy to make and can even be prepared in advance, I would say that in a pinch you could substitute your favorite jarred tapenade.

This is one of those recipes that once in your arsenal can be pulled off as a weeknight meal or trotted out to impress guests. As mentioned, it would be the perfect centerpiece of your holiday meal because it is basically hands-off at the time when you might be scrambling to finish things up and is just as good at room temperature as it is warm from the oven.

Bottom line, Slow-Roasted Salmon with Walnut-Olive Vinaigrette is super easy, impressive and delicious which is most definitely what catapulted it to the top of Food & Wine’s Best Of list. Enjoy!
