The Complete Recipe
Thank you for reading this far! Now, let’s dive into the actual recipe for this delightful Keto Lemon Butter Salmon with Roasted Radishes.
Keto Lemon Butter Salmon with Roasted Radishes
Ingredients
- 4 salmon fillets (about 6 oz each)
- 1 lb radishes, halved
- 4 tbsp unsalted butter
- 3 cloves garlic, minced
- Juice and zest of 1 lemon
- Salt and pepper, to taste
- Fresh dill, for garnish
Tip: Choose fresh, wild-caught salmon whenever possible for the best flavor and health benefits. For a low-carb twist, opt for radishes as they roast beautifully and add a crunchy texture!

Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). This temperature is perfect for roasting the radishes while keeping the salmon tender and moist. Get that oven nice and hot!
Step 2: Prepare the Radishes
In a mixing bowl, toss the halved radishes with 2 tablespoons of melted butter, salt, and pepper. Lay them out on a baking sheet in a single layer. This step is crucial as it allows them to roast evenly and develop a beautiful caramelization.
Step 3: Roast the Radishes
Roast the radishes in the preheated oven for about 15 minutes. They should be tender and slightly browned when done. Keep an eye on them, as oven times can vary!
Step 4: Prepare the Lemon Butter Sauce
While the radishes are roasting, melt the remaining 2 tablespoons of butter in a small saucepan over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute. Be careful not to burn the garlic! Stir in the lemon juice and zest, and season with salt and pepper.
Step 5: Add the Salmon
Remove the radishes from the oven and push them to one side of the baking sheet. Place the salmon fillets on the other side and drizzle them generously with the lemon butter sauce. Bake everything together for an additional 12-15 minutes, or until the salmon flakes easily with a fork.
Step 6: Serve and Enjoy!
Once everything is done, plate the salmon alongside the roasted radishes, and drizzle any remaining lemon butter sauce over the top. Garnish with fresh dill for a pop of color and flavor. Enjoy the delightful combination of flavors and textures!
