Vegan Mushroom Stroganoff with Lentils - Chaffer Recipe

Rich, deeply savory, and packed with umami — not an afterthought, but one of the most satisfying dishes on the spread

About This Recipe

Rich, deeply savory, and packed with umami flavor, this vegan mushroom stroganoff is the kind of vegetarian dish that holds its own on a buffet table — not an afterthought, but one of the most satisfying dishes in the spread.

A mix of caramelized mushrooms, hearty lentils, creamy coconut sauce, and herbs creates a comforting, meat-free main that stays rich and flavorful throughout buffet service. Scaled to generously fill a standard 13×9 inch catering pan, it's perfect for parties, holiday gatherings, and mixed-diet entertaining.

Ingredients 3 lbs cremini mushrooms, sliced 1 lb portobello or mixed wild mushrooms, sliced 2 large yellow onions, sliced 5 garlic cloves, minced 3 tbsp olive oil 2 tsp smoked paprika 1 tsp dried thyme 2 tbsp tomato paste 1 tbsp Dijon mustard ½ cup dry white wine (optional) 2 cans (13.5 oz each) coconut cream 2 cups vegetable stock 2 cans (15 oz each) green or brown lentils, drained and rinsed 2 tbsp soy sauce 1 tbsp white miso or nutritional yeast (optional) 1 tsp kosher salt, plus more to taste 1 tsp black pepper 1 tbsp lemon juice or sherry vinegar Fresh flat-leaf parsley, for garnish

Method

1. Brown the mushrooms: heat olive oil in a large Dutch oven over high heat. Cook mushrooms in batches until deeply browned and caramelized, 8–10 minutes per batch. Do not overcrowd the pan. Transfer to a plate.

2. Cook the onions: reduce heat to medium. Cook onions 8–10 minutes until softened and lightly golden. Add garlic, smoked paprika, and thyme; cook 1 minute until fragrant.

3. Build the sauce: stir in tomato paste and Dijon mustard; cook 1 minute. If using white wine, add now and simmer until mostly reduced.

4. Simmer: add coconut cream, vegetable stock, soy sauce, and miso if using. Bring to a gentle simmer for 10 minutes.

5. Finish the stroganoff: return mushrooms to the pot. Add lentils and simmer 10–15 minutes until rich and thickened. Stir in lemon juice or sherry vinegar. Season generously with salt and pepper.

6. Transfer to your 13×9 inch half-size catering pan. Garnish generously with fresh parsley.

Pro Tip
The key to deep, "meaty" mushroom flavor is proper caramelization. Don't salt the mushrooms too early and never overcrowd the pan — they need space to brown rather than steam. This step is worth taking your time over.

Chafing Dish Setup

• Stir gently every 30 minutes — coconut cream can separate if left undisturbed
  
• Refresh with a handful of fresh parsley every hour to keep it looking vibrant
  
• Serve over steamed rice or with warm dinner rolls on the side
  

Make-Ahead Tips
Make up to 2 days ahead and refrigerate. The lentils absorb the sauce as it sits — stir in a splash of vegetable stock when reheating to loosen it back up. Freezes well for up to 2 months.
