Ingredients for Baked Sausage and Peppers with Onions
Here’s the beautiful part—you probably have most of this already! I love recipes where I don’t need to make a special grocery run. Just gather:
- The stars of the show: 1 lb Italian sausage links (go spicy if you’re feeling bold!), 2 bell peppers (any color—I mix red and yellow for vibrancy), 1 large onion
- The flavor boosters: 2 tbsp olive oil (the good stuff!), 1 tsp dried oregano (rub it between your fingers to wake it up), ½ tsp salt, ¼ tsp black pepper
That’s it! No fancy ingredients, no complicated prep. Though I’ll confess—sometimes I sneak in a few cloves of minced garlic when no one’s looking. Shhh!
How to Make Baked Sausage and Peppers with Onions
Okay, let’s get down to business—this dish is so easy, you’ll laugh when you see how little effort it takes. First, preheat that oven to 400°F (200°C). While it’s heating up, grab your biggest mixing bowl—I like to use the one my grandma gave me, with the little chips in the enamel that prove it’s seen decades of good meals. Toss in your sliced bell peppers and onions, then drizzle with olive oil. Sprinkle over the oregano, salt, and pepper, and give it all a good mix with your hands. Yes, hands! You want every piece coated evenly, and fingers work better than any spoon.

Now, spread those gorgeous veggies in your baking dish—I use my trusty 9×13, but anything similar works. Nestle the sausage links right on top, spacing them out so they crisp up nicely. Pop it in the oven and let the magic happen for 25-30 minutes. You’ll know it’s done when the sausages are golden brown and the peppers are tender with those delicious caramelized edges. Oh, and your kitchen will smell like an Italian bistro—consider yourself warned!
Step 1: Prep the Vegetables and Sausage
Slice those bell peppers into strips—about ½ inch thick—so they cook evenly. For the onion, I like half-moons because they look pretty and caramelize beautifully. No need to peel the sausage links; just pat them dry so they brown nicely. Pro tip: If you’re short on time, buy pre-sliced peppers from the store—I won’t tell!
Step 2: Bake to Perfection
Bake until the sausages reach 160°F inside (use a meat thermometer if you’re nervous) and the veggies are fork-tender. If you love extra caramelization, broil for the last 2 minutes—just keep an eye on it! Want more veggie ideas? Check out this stuffed peppers recipe for inspiration.

Tips for the Best Baked Sausage and Peppers with Onions
After making this dish more times than I can count (hello, weeknight hero!), I’ve picked up a few tricks that take it from good to “wow, can you make this again tomorrow?” Here’s my cheat sheet:
- Sausage shuffle: Mix sweet and spicy Italian sausages in the same pan—the flavor contrast is incredible. Chicken or turkey sausage works too, just add an extra drizzle of oil since they’re leaner.
- Garlic glory: Toss in 3-4 minced cloves with the veggies. It’ll perfume the whole dish like your favorite Italian restaurant.
- Balsamic boost: Splash a tablespoon over everything before baking. The tangy sweetness cuts through the richness perfectly.
- Herb hack: Fresh rosemary or thyme sprigs tucked between sausages make it look (and taste) fancy with zero effort.
Oh, and don’t overcrowd the pan—give those sausages space to crisp up properly. Trust me, it makes all the difference!
Serving Suggestions for Baked Sausage and Peppers with Onions
Now comes the fun part—what to serve with your gorgeous baked sausage and peppers! This dish plays well with others, so let me share my favorite ways to turn it into a full meal. First up: crusty bread is non-negotiable in our house. There’s nothing better than using it to soak up those savory juices pooling in the baking dish. My kids call it “flavor bread” and fight over the last piece!
For heartier appetites, I love pairing it with creamy mashed potatoes—the perfect contrast to the caramelized veggies. Or try these garlic herb roasted potatoes for extra texture. When I want something lighter, a simple arugula salad with lemon dressing cuts through the richness beautifully. And if you’re feeding a crowd? Just double everything and let people make their own sausage sandwiches on hoagie rolls!

Honestly though? Sometimes we just eat it straight from the pan with forks. No judgment here—it’s that good.
Storage and Reheating Instructions
Oh, the leftovers! Honestly, they might be even better than fresh out of the oven. Let the baked sausage and peppers cool slightly (no lid—we don’t want soggy food!), then tuck everything into an airtight container. It’ll keep happily in the fridge for 3-4 days. To reheat? I either pop it back in a 350°F oven for 10 minutes (crisps up beautifully) or microwave single portions until hot—just stir halfway to evenly distribute those tasty juices. Pro tip: If the sausages seem dry, splash in a teaspoon of water before reheating. You’re welcome!
Nutritional Information
Now, I’m no nutritionist, but here’s the deal—this baked sausage and peppers dish packs plenty of protein and veggies, making it a hearty, balanced meal. Keep in mind, nutritional values can vary based on your sausage choice (turkey vs. pork, spicy vs. sweet) and how much olive oil you use. Those caramelized peppers? Loaded with vitamin C! Just remember, these numbers are estimates—your mileage may vary depending on brands and portion sizes. But honestly? Sometimes delicious comfort food is its own kind of nutrition.
Frequently Asked Questions
Can I use turkey sausage instead of Italian sausage?
Absolutely! Turkey sausage works great—just add an extra drizzle of olive oil since it’s leaner. The flavor will be slightly milder, so I like to bump up the herbs or add a pinch of red pepper flakes for kick. Chicken sausage works too—this recipe is all about making it your own!
How long do leftovers last in the fridge?
Your baked sausage and peppers will stay delicious for 3-4 days stored in an airtight container. Pro tip: Keep the sausages whole until you’re ready to reheat—they stay juicier that way. The flavors actually deepen overnight, making those leftovers something to look forward to!
Can I freeze this dish?
You bet! Freeze portions in airtight containers for up to 2 months. Thaw overnight in the fridge before reheating. The peppers might soften a bit, but the flavors hold up beautifully. I often double the recipe just to stash some in the freezer for emergency dinners!
What’s the best way to reheat leftovers?
My favorite method is reheating in a 350°F oven for about 10 minutes—it brings back that perfect crispness. If you’re in a hurry, the microwave works too (stir halfway through!). Just add a splash of water or broth if things look dry.
Can I add other vegetables to this dish?
Please do! Zucchini, mushrooms, or even cherry tomatoes are fantastic additions. Just keep the total veggie volume about the same so everything roasts evenly. My kids love when I throw in some sliced potatoes—makes it a complete one-pan meal!
