Ingredients

This recipe celebrates the purity of fresh ingredients, allowing each component to shine.

• 12 cups spinach, washed, stems removed
• 3 garlic cloves, minced
• Salt and pepper to taste
• 1 lb fillet of sole (about 4 fillets)
• 1 medium sweet onion, minced
• 4 roma tomatoes, sliced
• 2 jalapeno peppers, minced (optional, for a touch of heat)

Equipment Needed

You won’t need a lot of fancy gadgets for this recipe. The key here is proper parchment paper technique.

• Large pot with a lid (for wilting spinach)
• Oven
• Baking sheet or baking stone
• Parchment paper (about 12″x 18″ pieces)

Instructions

This method, known as ‘en papillote,’ is a fantastic way to cook fish. It steams the fish gently in its own juices, along with aromatics and vegetables, resulting in incredibly moist and flavorful results.

1. Begin by preparing your spinach. Place the freshly washed spinach into a pot with its lid. The residual water clinging to the leaves will be enough; you do not need to add any extra water. Steam the spinach until it is just wilted. This should take approximately 4 minutes. Once wilted, drain it thoroughly and allow it to cool enough so you can handle it comfortably.
2. Preheat your oven to 400°F (200°C).
3. Prepare your parchment parcels. Tear off 4 pieces of parchment paper, each measuring about 12″x 18″. Lay each piece of parchment flat on your countertop.
4. On the center of each parchment piece, place a quarter of the wilted spinach.
5. Next, top the spinach with an equal portion of the minced sweet onion, followed by the minced jalapeno peppers (if using), and finally the minced garlic cloves.
6. Carefully place one fillet of sole on top of the aromatic vegetable mixture on each parchment piece.
7. Crown each fillet with several sliced roma tomatoes.
8. Season each parcel generously with salt and pepper to your liking.
9. Now, carefully seal the packages. Bring the edges of the parchment paper together and fold them over multiple times to create a tight seal, ensuring no steam can escape. You want to create a well-sealed parcel.
10. Place the sealed parchment parcels onto a baking sheet or a baking stone.
11. Bake in the preheated oven for approximately 12 to 15 minutes.
12. To test for doneness, carefully test one package. The fish should be opaque and flake easily with a fork. The package itself will often be puffed out a bit when the contents are perfectly cooked.
13. To serve, carefully transfer the hot parcels to individual plates. The magic happens when each person gets to open their own surprise package, releasing the fragrant steam and revealing the beautifully cooked fish and vegetables.

Expert Tips & Tricks

Cooking en papillote is all about creating a self-contained steaming environment. Here are a few pointers to elevate your experience:

• Parchment Perfection: When sealing your parcels, aim for a tight, overlapping crimp all the way around. This ensures that the steam is trapped inside, cooking the fish gently and infusing it with the flavors of the aromatics. A loose seal will result in drier fish.
• Don’t Overcrowd: While you want a good amount of spinach, don’t overstuff the parcels. Too much volume can prevent even cooking.
• Vinegar for Vibrancy: If you like a little brightness, a tiny splash of white wine or lemon juice added to each parcel before sealing can enhance the flavors.
• Fish Flexibility: While sole is delicate and cooks quickly, this method works beautifully with other flaky white fish like cod, halibut, or tilapia. Adjust cooking time slightly based on the thickness of your chosen fillet.

Serving & Storage Suggestions

This dish is best enjoyed immediately after opening the parchment parcels, allowing your guests to experience the full aromatic impact.

• Serving: Present each parchment parcel directly on a plate. Encourage your guests to carefully unseal their own packet at the table for a bit of interactive dining. A side of crusty bread to soak up any delicious juices is always a welcome addition.
• Storage: Leftovers can be stored, but the parchment presentation is lost. Carefully remove the contents from the parchment paper and place them in an airtight container. Store in the refrigerator for up to 1-2 days. Reheat gently in a covered dish in the oven or on the stovetop over low heat to prevent drying out.

FAQs

Q: Why is it called “en papillote”?
A: “En papillote” is a French culinary term that translates to “in parchment.” It refers to the cooking method where food is sealed inside parchment paper or foil and baked.

Q: Can I use tin foil instead of parchment paper?
A: Yes, you can use heavy-duty tin foil, but parchment paper is generally preferred as it’s less likely to react with acidic ingredients and allows for a more even steam.

Q: How do I know if the fish is cooked without opening the package?
A: The package will typically puff up significantly when the fish is done. A gentle squeeze on the parcel will also feel less resistant, and you can sometimes see the steam escaping if the seal isn’t perfect. For certainty, testing one package is always recommended.

Q: Can this recipe be made ahead of time?
A: You can assemble the parcels a few hours in advance and keep them refrigerated on a baking sheet. Bake them just before serving for the best experience.

Q: What kind of sole should I use?
A: While any fillet of sole works, ** Dover sole** or lemon sole are excellent choices for their delicate flavor and flaky texture. However, other mild white fish are perfectly suitable.
