This simple side dish of roasted asparagus and potatoes, tossed with a garlicky, herby butter mixture and Parmesan cheese, makes the most of early spring asparagus and baby red potatoes.
Oven-roasted with garlic and herbs, and then sprinkled with Parmesan cheese, this is one vegetable side dish that everyone loves.
In case you hadn’t noticed, I’m convinced that roasting even the most boring of vegetables is the absolute key to unlocking their flavor. See these maple balsamic roasted brussels sprouts and oven-roasted sweet potatoes with brown butter, or this roasted cauliflower with cumin and coriander for proof.
Not that I would dare to call potatoes boring, I mean they make the perfect side dish with so many meals – and there is just so much you can do with them! Fry them, boil them, bake them, roast them – they are delicious whatever you do.
Roasting asparagus on the other hand is a revelation! Briefly baked to crisp-tenderness with flavorful ingredients, asparagus to me just tastes like spring, and baby, or new, potatoes are their perfect partner.
Asparagus also happens to be jam-packed with vitamins, minerals, and antioxidants. It’s also extremely low in calories and perfect for lighter spring dishes.
Which potatoes are best for roasting?
I love baby red potatoes for this baked asparagus and potatoes recipe. Their waxiness helps maintains a creamy inside, and their thin skin allows for good heat transfer.
If you can’t find baby red potatoes, you can also use baby yellow potatoes, or regular red or yellow potatoes, cut into 1 inch pieces.
I prefer the creaminess of the waxier red or yellow potatoes in this recipe, but russet potatoes will also roast up nicely, if a little softer.
How to trim asparagus
The lowest section of the asparagus is quite woody and tough to eat. Finding the natural cutting point and then just bending the asparagus to break it is an easy technique to remove this woody part.
It should snap off at the right place, but to avoid waste, aim to snap where the green part of the stalks begins to fade to white.
Alternatively, you can simply place a bunch on a cutting board and use a knife to chop off about 1-2 inches from the end.
You can save these woody scraps to flavor stocks and broths. Just keep them in a freezer bag in the freezer with other vegetable scraps, and throw them in a pot of water to make a simple vegetable stock.
Apart from the obvious heroes of the dish – the fresh asparagus and potatoes, this roasted red potatoes and asparagus dish only requires a handful of other ingredients.
Olive Oil & Butter: I usually roast vegetables with only olive oil, but in the case of potatoes I find that adding in some butter aids with browning and flavor. Feel free to alter the ratios, or just skip the butter.
Spices & Seasoning: To season the vegetables, I love fresh thyme, salt, and pepper, and of course, a healthy amount of garlic. If you don’t like thyme, try replacing another fresh herb. Finely chopped rosemary, or a combination of the two works well.
You can also use about 1.5 teaspoons of dried herbs or Italian seasoning if you don’t have fresh herbs on hand.

Frequently asked questions
Red potatoes have a rich and earthy flavour that’s perfect for roasting. It is also a waxy potato that has high moisture and low starch content, which means its shape doesn’t change much during cooking.
You should wash your red potatoes to remove any dirt from the surface. However, whether or not you peel them is your own choice. I would advise you to leave the skin on and not peel them. The skin contains a lot of nutrients. It also crisps up while it cooks in the oven, giving the roasted asparagus and potatoes a lovely texture.
Asparagus has a low calorie count and is high in vitamins, minerals, and antioxidants, vitamins A, C, E, K, B6 (folate), fibre, copper, iron, calcium, and protein. It can also help with digestion, making it an excellent vegetable to include in your diet!
