Smoky Roasted Pepper Lasagne is my go-to vegetarian comfort dish whenever I want to impress a table of friends or bring warmth to a quiet family dinner. The sweetness from roasted peppers melts into fire-roasted tomato sauce, while chipotle flakes and smoked paprika layer in that irresistible smoky depth – this is definitely not your average lasagne.

Every time I make this recipe my kids fight over the crispy baked edges and my husband swoons at the luscious cheese topping. This dish first became a winter staple during our year of meatless Mondays and has remained an all-time favorite ever since.

Ingredients

  • Red bell peppers: The star ingredient for deep sweetness and roasted flavor Look for bright firm peppers for best results
  • Canned plum tomatoes: Give the sauce body and classic Italian touch San Marzano style tomatoes work especially well
  • Dried porcini mushrooms: Add earthy richness to the ragu Choose plump pieces and soak in very hot water
  • Red onion: Gives the sauce a sweeter base than yellow or white onions
  • Garlic: Essential for aromatic warmth Use fresh and avoid pre-chopped jars for best flavor
  • Bay leaf: Infuses a subtle herbal background Remove before layering
  • Chipotle flakes: Bring smoky and gentle heat Start with less if you want less spice
  • Quorn mince: Provides hearty texture and protein A freezer staple for quick vegetarian meals
  • Lasagne sheets: Use dried for structure or fresh sheets for extra tenderness
  • Butter: Creates luscious white sauce Opt for good quality creamy butter
  • Flour: Thickens your béchamel sauce and creates a smooth base
  • Whole milk: The key to a silky creamy sauce Use full-fat milk for best taste
  • Smoked paprika: Doubles down on the smoky layers Choose high-quality Spanish paprika
  • Cheddar cheese: Melts into sharp tang in the white sauce Grate freshly for best melting
  • Mozzarella: finishes the bake with gooey bubbles and stringy charm
  • Salt and pepper: To balance and brighten all the other flavors Freshly ground pepper adds more aroma

Roasting the peppers brings out an amazing smoky sweetness you just cannot fake My favorite memory is letting my daughter help peel the roasted peppers as the kitchen filled with that sweet aroma

Storage Tips

Leftovers keep perfectly in the refrigerator for up to four days I like to portion slices into containers so weekday lunches are grab and go To reheat microwave is fine but oven brings back the best texture

Ingredient Substitutions

You can swap out Quorn mince for any plant-based ground alternative or skip it for lots of sautéd mushrooms If you cannot find dried porcini use fresh cremini mushrooms with a splash of soy sauce For a vegan version opt for plant-based cheese and plant milk

Serving Suggestions

A wedge of this lasagne pairs beautifully with a crisp green salad and a punchy vinaigrette My family loves it with garlicky steamed broccoli or simply a slice of rustic bread to mop up the sauce

Recipe FAQs
