This recipe, rooted in Russian home cooking, transforms simple pantry staples into a restaurant-worthy meal that feels both comforting and refined.

Served on a bed of lightly dressed salad greens, it makes a complete, elegant dinner that comes together in under 30 minutes.
About This Dish
Cod has long been a favorite in Russian cuisine for its mild taste and firm texture, which stands up well to baking. Paired with wild mushrooms and bacon, the dish gains a hearty, almost rustic character. The technique of partially pureeing the mushroom mixture creates a paste that adheres to the fish, ensuring every bite is infused with flavor. This recipe is perfect for weeknight dinners or entertaining, as it requires minimal hands-on time and delivers maximum impact. For those who value precision in the kitchen, using a high-quality immersion blender or a glass food processor can make the puree step effortless.
Ingredients
- 4 cod fillets (200 g each)
- 4 slices bacon
- 200 g oyster mushrooms
- 1 garlic clove
- Olive oil, salt, pepper, and mixed salad greens (optional)
All ingredients are widely available. For the best results, choose thick, center-cut cod fillets and fresh oyster mushrooms. If you’re using a quality oil sprayer, you can control the amount of oil precisely for that golden crust.
Step-by-Step Instructions
Step 1: Prepare the mushroom-bacon puree.
Cut the bacon into small pieces and slice the mushrooms into thin strips. Heat a large non-stick skillet over medium heat and fry the bacon for 3 minutes until it begins to crisp. Add half the mushrooms and cook, stirring frequently, for 5 minutes until they release their liquid and start to brown. Transfer the mixture to a blender jug and pulse until you get a coarse puree. Season with salt and pepper. A powerful food processor or blender works best here; you want a spreadable consistency, not a smooth paste.
Step 2: Assemble and bake the cod.
Preheat your oven to 190°C (375°F). Line a baking dish with parchment paper. Place the cod fillets in the dish and spread the mushroom-bacon puree evenly over each fillet, pressing it down gently with a spatula. Drizzle with a little vegetable oil and bake in the center of the oven for 12–15 minutes. Then increase the temperature to 210°C (410°F) and bake for an additional 4 minutes, until the crust turns golden and crisp. An oven with even heat distribution ensures the fish cooks uniformly.
Step 3: Sauté the remaining mushrooms and serve.
While the fish bakes, heat a drizzle of olive oil in the same skillet and sauté the remaining mushrooms for 4 minutes. Add the minced garlic and a handful of mixed salad greens, season with salt and pepper, and cook for another 1–2 minutes until the greens just wilt. Arrange the mushroom-greens mixture on plates, place a cod fillet on top, and serve immediately. For a truly non-toxic cooking surface, consider a non-toxic air fryer as an alternative to baking.
Tips for Perfect Cod
- Don’t overcook: Cod is done when it flakes easily with a fork. The high-heat finish creates a crunchy crust without drying out the fish.
- Use a thermometer: For precise results, aim for an internal temperature of 63°C (145°F). A digital thermometer (though designed for fridges) can also be used for meat probing—or better yet, a proper instant-read probe.
- Let it rest: Allow the fish to rest for 2 minutes after baking to redistribute juices.
- Bacon quality matters: Thick-cut, naturally smoked bacon adds the most depth.
Variations
- Mushroom mix: Swap oyster mushrooms with shiitake, cremini, or porcini for different savory notes.
- Herb infusion: Add fresh thyme or rosemary to the puree for an aromatic twist.
- Cheese topping: Sprinkle grated Parmesan or Gruyère over the crust during the last 5 minutes of baking.
- Vegetarian version: Replace cod with thick slices of portobello mushroom or firm tofu, and omit the bacon.
- Cooking method: Use a countertop convection oven for faster, more even browning, or try a microwave pressure cooker for a quicker version.
FAQ
Can I use frozen cod?
Yes, but thaw it completely in the refrigerator and pat it dry with paper towels to remove excess moisture. This ensures the crust adheres properly.
What if I don’t have oyster mushrooms?
Button mushrooms, shiitake, or even canned mushrooms (drained) can work. For the best texture, fresh mushrooms are preferred.
How do I store leftovers?
Store baked cod in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven (150°C) or an air fryer at 175°C for 3–4 minutes to restore crispness.
Can I make the mushroom puree ahead of time?
Absolutely. Cook the bacon and mushrooms, puree, and refrigerate for up to 3 days. Bring to room temperature before spreading on the fish.
What wine pairs well with this dish?
A dry white wine such as Sauvignon Blanc or a light Chardonnay complements the richness of the bacon and mushrooms. For a more adventurous pairing, try a sweet high-alcohol wine like a late-harvest Riesling for contrast.
Is this recipe gluten-free?
Yes, as long as you use gluten-free bacon and check that your salad greens are not cross-contaminated.
Can I substitute the bacon with another meat?
Smoked turkey or prosciutto can be used, but the fat content is lower, so you may need to add a tablespoon of butter or oil to the puree.
How do I prevent the fish from sticking to the parchment paper?
Lightly oil the parchment or use a reliable oil sprayer to create an even non-stick layer.
