Instructions for Making Roasted Red Pepper and Spinach Lasagna

Making this lasagna is like building edible art — layers of flavor and texture. Let’s get started.

1. Preheat Your Equipment:
   Preheat the oven to 375°F (190°C). Lightly grease your baking dish.

The beauty of this lasagna lies in its layers — the creamy ricotta contrasts the chewy noodles, while the roasted red peppers bring bursts of sweetness. The spinach blends in seamlessly, adding both texture and color. Each bite is cheesy, saucy, and perfectly balanced.

Cooking Tips & Tricks

A few tricks can take your lasagna from good to unforgettable.

• Use freshly grated cheeses — they melt better and taste fresher.
