Frozen salmon or fresh salmon?

Frozen salmon is ideal for parcel dishes because it steams gently inside the sealed parchment, and the slow cooking forgives a slightly longer time. Just rinse the frozen salmon briefly under cold water, pat dry and place it into the parcel still frozen. Cooking time: 20 minutes at 200 degrees Celsius. Fresh salmon works just as well. Pat dry and place into the parcel, then reduce the cooking time to 15 minutes. If you prefer to thaw frozen salmon first, leave it in the fridge for 12 hours. Always choose fillets without glaze and look for MSC or ASC certification.

Preparation

Slice the zucchini and arrange the slices on a piece of parchment paper. Place the salmon on top, then add cherry tomatoes, oregano, olive oil and lemon juice. Fold the parchment paper into a tightly sealed parcel and bake at 200 degrees Celsius for 20 minutes.

Why salmon parcels work well on keto

Zucchini has just 2 g net carbs per 100 g, making it one of the lowest-carb vegetables and an excellent keto side. Cherry tomatoes (50 g) add about 2 g of carbs, easy to fit at this amount. Olive oil (2 tbsp) delivers 28 g of high-quality fat. Combined with 200 g of salmon (40 g protein, 0 g carbs), the result is a Mediterranean meal well under the 7 g net carb limit per serving.

Cherry tomatoes and keto

Cherry tomatoes have approx. 3 g net carbs per 100 g, slightly more than other salad vegetables. In portions under 75 g they fit keto comfortably and provide lycopene, which is well absorbed when heated.

How do I serve and vary the salmon parcels?

Place the parcel directly on the plate and open it at the table; the escaping steam carries the Mediterranean aromas. From personal experience, a simple arugula salad with olive oil dressing pairs perfectly.

Vegetable variation

Instead of zucchini you can use fennel, eggplant slices or thinly sliced bell pepper (keep the amount around 50 g). For asparagus: 3 spears per parcel, halved.

What tips help with parcel cooking?

  • Cut parchment paper at least 30 x 40 cm so the parcel does not tear.
  • Slice zucchini 5 mm thin so it cooks through in 20 minutes.
  • Fold the parcel tightly; the moisture inside gently cooks the salmon.
  • Use frozen salmon without thawing; the parcel handles the longer cooking time.
  • Open carefully: the hot steam escapes first.

FAQ

Can I use fresh salmon instead?

Yes. Fresh salmon works just as well. Reduce the cooking time to 15 minutes at 200 degrees Celsius.

Can I use aluminum foil instead of parchment paper?

Possible, but parchment paper is better: aluminum foil can react with the acids from tomato and lemon. Parchment paper avoids that reaction.

How do I know the salmon is done?

After 20 minutes at 200 degrees Celsius the salmon is done when it flakes easily with a fork. A core temperature of 52 to 55 degrees Celsius gives a juicy result.

Can I prepare the parcel in advance?

Yes. The filled parcel keeps in the fridge for 4 hours and stays keto-friendly. Place it in the preheated oven just before serving.
