The Unexpected Ingredient Your Salmon Is Missing
This is rhubarb roasted salmon and if youโre sitting there thinking, “Rhubarb… on fish?” I get it. It sounds a little wild at first. But think about how amazing salmon tastes when you pair it with a squeeze of fresh lemon or a sweet glaze. Salmon is a rich, buttery fish, so it naturally craves contrast.
Thatโs where the rhubarb comes in. Because it has that sharp, natural tang, it cuts right through the richness of the salmon. When you roast it, the sauce caramelizes onto the fish, turning into this sticky, smoky, sweet-and-savory glaze that is out of this world. Itโs not just a unique recipe; the flavors genuinely balance each other out perfectly. One bite and you’ll completely get it. If you love this flavor combination and have some chicken in the fridge, you’ve got to try my rhubarb bbq chicken. Or, if you’re just looking for more easy fish dinners, definitely check out my sweet chili salmon .

P.S. If you’re wondering about that creamy side dish in the photo, it’s my viral Southern Coleslaw. It has the perfect crunch and goes beautifully right alongside this flaky salmon!
What You’ll Need For This Recipe
To make this roasted salmon, the ingredient list is incredibly short because my homemade rhubarb bbq sauce does all the heavy lifting.
- Salmon Fillets: You can use individual center-cut fillets or one large side of salmon. Skin-on helps keep it juicy!
- Olive Oil: Just a little bit to coat the fish.
- Salt, Pepper, and Garlic Powder: A simple base layer of seasoning before the glaze goes on.
- Rhubarb BBQ Sauce: You’ll want about 1 cup of my Homemade Rhubarb Barbecue Sauce. You can grab that full recipe to make it from scratch, or use a batch you’ve already frozen.
