White Fish with Herb Butter over Spinach

This delicious fish recipe is easy to prepare and quick to make. We use tilapia filets, which are a perfect blank canvas for our rich homemade herb butter, and they can stand up to the broiler after they have been sous vide. The herb butter is endlessly adaptable based on whatever herbs you have on hand. We loved tarragon when we tested this recipe any leafy herb will work. Be sure to top the tilapia with the herb butter while the fish is still hot so that the butter can melt and the herbs can aromatize.

Note: Save any leftover herb butter for grilled meats, vegetables, or toasted bread.

Suvie Cook Settings

Bottom Zone: Sous Vide 120°F for 30 minutes

Top Zone: Steam for 5 minutes

3) While the fish cooks, prepare the herb butter. Ensure the butter is soft and malleable. If not, microwave for 10 seconds on 50% power to soften. In a small bowl, stir together 4 tbsp butter, 2 tbsp minced herbs,  ½ tsp salt, and ¼ tsp pepper

4) After the fish has finished cooking, remove all pans from your Suvie. Remove tilapia from vacuum bags, and pat dry. Pour off water from the pan and place a greased Suvie roasting rack inside. Place tilapia on the rack and return pan to Suvie. Broil fish for 10 minutes, or until the tilapia begins to flake.

5) Divide spinach evenly between plates, drizzle with olive oil, and season to taste with salt and pepper. Place broiled tilapia filets on top of the spinach and immediately top with herb butter.
