This roasted cauliflower and potato recipe is a great side dish and such a winning flavor combo. Both vegetables roast so well AND go so well together. I love that they both have a mild flavor and pick up the flavor of spices so well.
Potatoes and cauliflower caramelize beautifully which makes all the difference when choosing a vegetable for a sheet pan roast. This side dish is easy to make and perfect for a quick dinner kind of evening.
Let me show you how to make it.
Ingredients needed
There are only a few ingredients you will need to make this:
- Cauliflower: This is one of the stars of this recipe.
- Red potatoes: Red potatoes roast up very well so I prefer them in this recipe. You can also use golden potatoes if that is what you have on hand.

- Turmeric: It adds so much flavor and beautiful color.
- Cumin: Cumin adds flavor and an earthy note to the veggies.
- Kosher salt: To enhance the flavor.
- Garlic: Fresh diced garlic cloves pair so well with cauliflower and potatoes.
I would bet you already have most of the spices for this roasted cauliflower and potatoes recipe in your pantry.

Why roasting vegetables is better
If you are not familiar with roasting vegetables, the roasting process really helps create a deep rich flavor and sweetness that you would not get from boiling and steaming.
I love the roasting process because it brings out the natural flavors of the vegetables and it also adds a delicious caramelization to them. When you make this roasted cauliflower and potatoes recipe, you will see what I mean.

Storing
I love making a big batch of these veggies to eat during the week. To store them just let them come to room temperature then place them in an air-tight container in the fridge for up to 3 days. You can easily reheat these in the microwave.
Faqs
No! You are going to fully cook the potatoes in the oven. To make sure the cauliflower and potatoes cook at the same time, you cut the potatoes into smaller pieces.
This is one that a lot of people struggle with and there are a few things you can do to achieve a perfectly crisp potato.
The first thing you want to do is make sure you are using a high heat when roasting. Always make sure to toss your veggies and potatoes halfway through the cooking process.
