I’m all for making life easier. At the end of the day, a sink full of dirty dishes and pans just isn’t relaxing. We’ve been obsessed with healthy one pan dinners lately. Less dishes, more nutrition. I call that a win-win.
Our healthy one pan dinner (yes, you read that correctly – only one pan) is a perfect dinner for weeknight meals and is an absolute dream. It’s an easy sheet pan dinner full of nutritious fresh vegetables and lean protein.

Ingredients in Healthy One Pan Dinner
This sheet pan dinner can be used with any vegetables and meat you have in your refrigerator, which makes it so easy. I’ll tell you how we made ours, but know that this quick dinner idea can be changed or modified with whatever healthy dinner ingredients you have on hand.
- Fresh mushrooms: We love the complex flavor mushrooms deliver to this one sheet pan dinner. If you aren’t a fan of mushrooms, feel free to omit these and add another vegetable you might enjoy more.
- Bell Peppers: Bell peppers offer many nutritional benefits and are rich in antioxidants. I used green and orange in our sheet pan meal but you can use any color!
- Purple cauliflower: I love using purple cauliflower in recipes instead of white cauliflower. It provides all the flavors of cauliflower, but with a vibrant purple color in my meal.
- Onion: We prefer using a sweet onion in this recipe, however you can use any color onion you have on hand for this baking sheet meal.
- Zucchini: I love zucchini, but if you aren’t a fan, you can always swap it out with another green vegetable like broccoli, Brussels sprouts, asparagus, or green beans.
- Mini-potatoes: We love tiny fingerling potatoes. Look for a blend that has a combination of purple, yellow, and red potatoes. The colors of all potatoes will give a slightly different flavor and look vibrant and colorful on your baking sheet.
- Chicken sausage: We prefer using chicken sausage in this delicious recipe due to the fact that it is a leaner meat. We love finding chicken sausages that are seasoned with Italian, red pepper and garlic flavors. This is a lean protein with minimal effort and minimal cleanup. We usually try to keep chicken sausage in our dinner rotation. You could sub in chicken breast or chicken thighs for this recipe. Just note that the healthy eating plan points would need to be recalculated.

How to Make Healthy One Pan Dinner in the Oven

Step 1: Chop all of your veggies up small. Small is the key to even cooking, especially for the potatoes! Make sure all of the veggies are roughly the same size.
Spray olive oil in the bottom of your baking dish and set your oven to 375º F.

Step 2: There are a couple different ways that you can cook the sausage.
I prefer to grill my sausage and then add it to the vegetables after they’re done cooking.
You can also add the sausage to the casserole and cook them all together to truly make this a one pan dinner.

Step 3: Check your veggies after 20 minutes, and every 5 minutes after that until they’re done. I used a fork to see how soft the potatoes and cauliflower were before pulling them out of the oven.

Step 4: Serve warm.
Recipe Tips
- If you are using meat that is already cooked you can choose to include it before or after the veggies go into the oven. Leftover rotisserie chicken is great in this healthy casserole recipe!
- This is a great recipe for meal prep. It’s one of those one pan meals that you can meal prep ahead of time and portion out according to your container needs for the day.
- I love how versatile this recipe is! I take whatever veggies we have in the fridge and pair them up with whatever protein we have hanging around. It doesn’t matter if you are working with chicken breast or roasted chicken or the chicken sausage, it all comes together great!

- For your sausage, you could add it to the baking dish if you're cooking a smaller batch of vegetables. We were feeding four, so I cooked the sausage on the grill (which is our favorite, anyway). When the sausage was done, I added it to the top of the vegetables. 2 chicken sausage
