About This Dish
Baked cod with potatoes and mushrooms in a roasting bag is a classic Russian technique that marries the delicate sweetness of cod with the savory depth of champignons and buttery potatoes. The sealed bag creates a micro‑steam environment, ensuring the fish stays moist while the vegetables absorb every drop of juice. It's a one‑bag wonder—minimal cleanup, maximum flavor. For those who love precision, a wall oven microwave combo with air fryer offers versatile cooking modes. Pair with a crisp white wine like sweet wine with high alcohol content for a delightful contrast.
Ingredients
- Gutted cod (head removed): 1.3–1.5 kg
- Champignons (white mushrooms): 400 g
- Potatoes with thin skin: 500 g
- Clarified butter (ghee): 40 g
- Salt and freshly ground black pepper to taste
For best results, use the freshest cod and store‑bought au jus for prime rib isn't needed here—the natural juices are enough. But if you want extra depth, a drizzle of organic vodka can be added before sealing.
Step‑by‑Step Guide
- Preheat and prepare the bag. Preheat the oven to 190°C (top‑bottom heat, no convection). Line a baking sheet with parchment paper. Cut a 50 cm length of roasting bag film. Rub the cod inside and out with salt, pepper, and clarified butter. Best oil sprayer can help apply thin, even layers of butter.
- Slice the potatoes. Wash the potatoes and cut into thin rounds (2 mm thick). Season with salt and pepper. For uniform slices, a food processor for nut butter can be repurposed with a slicing disc, though manual slicing works fine.
- Prepare the mushrooms. Twist off the stems and chop them finely. Leave the caps whole, but score a cross on top. This helps release moisture and absorb flavors. If you own a best planetary mixer, the paddle attachment can quickly chop stems.
- Layer the bag. Clip one end of the roasting bag. Place a layer of potato rounds on the bottom (the side with tiny holes, if any, should be on top). Place the cod on the potatoes and arrange the mushroom caps and chopped stems around and inside the fish. Secure the open end with the second clip.
- Position and puncture. Place the bag on the prepared baking sheet. If the bag doesn't have pre‑made holes, poke a few with a needle or toothpick to allow steam to escape gently. For precise temperature monitoring, consider a refrigerant leak detector—though here it's about oven thermometer accuracy.
- Bake. Place the baking sheet in the center of the preheated oven. Bake for 40 minutes. The bag will puff up and the aroma will be irresistible. After baking, let it rest 5 minutes before cutting open. Serve directly from the bag for a rustic presentation. For a crispier finish, finish under the broiler setting of a wall oven microwave combo with air fryer.
Tips for Perfect Results
- Use clarified butter to avoid burning; it adds a nutty flavor. A non‑toxic immersion blender can help emulsify butter sauces.
- Don't skip the potato layer underneath—it prevents the fish from sticking and absorbs juices.
- For even cooking, slice mushrooms uniformly. A food processor for nut butter with a slicing disc works wonders.
- If you prefer a smoky char, transfer the cooked fish to a non‑toxic air fryer for 3–4 minutes.
- Store leftovers in a 48‑inch built‑in refrigerator with proper humidity control.
Variations to Try
Replace champignons with porcini or shiitake for a deeper flavor. Swap potatoes with sweet potatoes or parsnips. Add fresh herbs like dill or thyme inside the fish. For a dairy‑free version, use olive oil instead of clarified butter. Serve with a side of Catalan sponge cake for a sweet finish. Or drizzle with chocolate‑covered raisins for an indulgent twist.

Can I add other vegetables?
Absolutely! Carrots, bell peppers, or zucchini work well. Cut them similarly to ensure even cooking.
