A super easy and healthy potato bake with vegetables and melty cheese! This Vegetable Potato Bake is a versatile side dish that goes well with so many meals.
This easy and delicious side dish features thinly sliced potatoes, zucchini, tomatoes, and carrots in a delicious sauce, baked until perfectly tender, then topped with melted mozzarella cheese.
It’s one of my favorite dishes, and I know it will become one of yours too.
There are so many different ways to cook potatoes, like mashed potatoes, crushed potatoes, air fryer roasted potatoes, and more!
And while potatoes are amazing on their own, they are even better when paired with healthy fresh veggies, a savory tomato sauce, and cheese. This veggie potato bake has all of that, and it’s super simple to make.
Why You’ll Love This Vegetable Casserole Recipe
- It’s a favorite at my house, and it will be at yours too! I first shared this recipe here in 2016. This new recipe is exactly the same, but I’ve made some small adjustments to make it totally fail-proof. I’ve also updated the pictures and included step-by-step photos for you.
- Simple, fresh ingredients make this a healthy side dish. You can use veggies from your backyard garden if you have them, or just pick up these staples from the grocery store.
- It’s perfectly cheesy! A topping of mozzarella cheese makes everything more delicious. Try this veggie bake with other types of cheese too, like gruyere or swiss.
Key Ingredients
- Tomato Sauce: Use regular unseasoned tomato sauce or Italian passata for this dish. You don’t want the sauce to overpower the natural deliciousness of the veggies here.
- Garlic, Onion, and Thyme: These aromatic vegetables and herbs go perfectly with this dish. Choose fresh thyme for the best flavor.
- Thinly Sliced Potatoes: Use a mandoline or the slicing blade of your food processor to slice your potatoes into ⅛-inch rounds. This is key to the recipe, as thicker slices won’t cook all the way through.
- Carrots, Zucchini, and Tomatoes. Slice the carrots into ⅛-inch rounds as well. The zucchini and tomatoes can be thicker, about ¼-inch thick. Once you have all the veggies sliced, you’re ready to put them together into the best potato vegetable casserole side dish!

How To Make Cheesy Vegetable Potato Bake
Start by making a simple tomato sauce, then mix it with thinly sliced potatoes and veggies, and bake! This recipe is so easy, you’re going to love it.
- Saute: To start the sauce, heat olive oil in an ovenproof skillet, and saute sliced carrots and onions for a few minutes until the onions are soft and translucent. Then add the garlic and saute for just 30 seconds, or until fragrant.
- Make the Sauce: Add tomato sauce, water, and fresh thyme to the skillet. Stir and cook for 1 minute to combine. Taste, and add salt and pepper if needed.
- Add Potatoes and Veggies to the pan, and stir gently with a rubber spatula to cover the vegetables with the sauce.
- Bake: Cover with a lid or foil, and take in a preheated 375°F/190°C oven for 30 minutes. After 30 minutes, remove the lid and bake, uncovered for 5 minutes, or until the potatoes are soft. Add the mozzarella cheese, and broil for 3-5 minutes to melt.
Tip!
You may need to add a bit of extra baking time to get the potatoes cooked all the way. You’ll know they’re done when they’re easily pierced with a fork!
Recipe Tips
- Choose your Baking Dish: I’m baking this veggie bake in a deep, round, 12-inch enameled skillet with a lid. You can also bake your casserole in a 9×13-inch baking pan or another oven-proof skillet covered in foil.
- Use starchy potatoes. In the UK you’ll have the best results with Maris Piper potatoes, or go for Russet Potatoes or Sebago potatoes. Avoid waxy potatoes for this recipe.
- You don’t have to peel the potatoes! If you’d like to leave the skins on, just be sure to scrub the potatoes well.
- Sauteeing the carrots and onions helps to soften them and pull out their natural sweetness. If you’re short on time, you can skip this step, but you might find that the veggies have a bit more bite to them.
- When stirring the veggies into the sauce, use a rubber spatula, and be gentle so that you don’t break the potato slices too much.
- Garlic can burn if sauteed for too long. It only needs about 30 seconds in the pan. Beready to add the tomato sauce to slow down the cooking process.
Storing Tips
Keep leftovers in the fridge in an airtight container for 3-4 days. You can reheat portions in the microwave, or reheat the entire casserole in a 350°F/180°C oven until heated through.
If you’d like to make this vegetable potato bake ahead, prepare the sauce, mix in the veggies, then cover and place in the fridge overnight. Bake as directed when you’re ready.

Potatoes might be seen as a “less healthy” vegetable, but potatoes are actually fat-free, gluten-free, and have high nutritional content! They’re also 100% natural, salt-free, low in sugar, and a great source of fiber and potassium.
