📖 Instructions

1. Prep Your Oven and Pan: First things first, get your oven preheating to a solid 400°F (200°C). This high heat is key for getting those gorgeous caramelized edges on your veggies and sausage. While it heats up, grab a large, sturdy baking sheet. To make cleanup a breeze (and really, who doesn't love that?), line it with parchment paper. If you don't have parchment, a light spray of cooking oil will also work, but parchment is truly your best friend here!
2. Chop Your Veggies: Now, for the colorful stars of the show! Take your bell peppers (any color works, but a mix is so pretty!) and carefully remove the cores and seeds. Slice them into nice, thick strips, about 1/2 to 3/4 inch wide. Next, peel your onion and slice it into similar-sized wedges. We want them substantial enough to stand up to the roasting. Place all your chopped peppers and onions into a large mixing bowl.
3. Slice the Sausage: For the sausage, if you're using fresh Italian sausage links, cut them into 1-inch thick coins. If you're using pre-cooked sausage, you can cut them similarly or even halve them lengthwise if they are thicker. Add the sliced sausage to the bowl with your chopped vegetables.
4. Season Everything Up: Drizzle 2 tablespoons of olive oil over the sausage and veggies in the bowl. Sprinkle generously with 1 teaspoon of dried oregano, 1/2 teaspoon of garlic powder, and a good pinch of salt and black pepper. Now, get your hands in there (or use tongs!) and toss everything together really well. You want every piece of sausage and every veggie strip to be lightly coated in that delicious oil and seasoning. Don't be shy – make sure it's all mixed evenly.
5. Spread it Out: Pour the seasoned sausage and vegetable mixture onto your prepared baking sheet. This is crucial: spread it out into a single, even layer. Seriously, resist the urge to pile it high! If the pan is too crowded, the vegetables will steam instead of roast, and you'll miss out on that amazing caramelization and tender-crisp texture. If you have a smaller baking sheet, it's better to use two sheets to ensure everything has enough space.
6. Roast to Perfection: Slide that sheet pan into your preheated 400°F (200°C) oven. Let it roast for 20 minutes. After 20 minutes, pull the pan out and give everything a good stir with a spatula or tongs. This helps ensure even cooking and browning. Pop it back in the oven for another 15-20 minutes, or until the vegetables are tender-crisp and slightly charred at the edges, and the sausage is beautifully browned and cooked through.
7. Optional Finishing Touch & Serve: Once it's done, remove the pan from the oven. If you want a little extra brightness, you can sprinkle some fresh chopped parsley over the top. My secret little trick for an added pop of flavor is a tiny drizzle of balsamic glaze (just a touch!) right before serving. Serve hot, straight from the pan! It's fantastic on its own, with some crusty bread for dipping, or over rice or quinoa. Enjoy your easy, delicious dinner!
