Easy Mushroom-Shaped Potatoes for a Crispy Bistro-Style Side Dish
These mushroom-shaped potatoes are small potatoes carved to look like little mushrooms, then blanched, roasted, and finished with garlic, butter, and parsley. They are not a creamy potato dish, not a gratin, and not a simple baked potato. This is more of a decorative bistro-style potato garnish for roast meat, fish, grilled chicken, or a holiday-style plate that still works any time of year.
This recipe is based on my YouTube video, with a few adjustments since publication. In the video, I cook them at a lower oven temperature, but I now prefer a hotter oven because the potatoes brown better, lose less moisture, and come out less oily. What I look for here is a potato that keeps its mushroom shape, has a lightly golden surface, and smells of butter, garlic, parsley, and bay leaf when it comes out of the pan.
The mistake to avoid is cutting too deep when forming the stem. If the circular cut goes too far into the potato, the little mushroom cap can separate from the base. The second mistake is not drying the potatoes properly after blanching. Wet potatoes steam in the pan. Dry potatoes roast and color.
Why I Make These Potatoes This Way
I make it this way because the blanching step removes some of the surface starch before the potatoes hit the hot oil. That matters. If the carved potatoes go straight into the pan raw, they can stick together, brown unevenly, and sometimes break when you try to move them.
The brief boil also gives the potatoes a small head start without fully cooking them. They are still firm when drained, but the outside has softened just enough to roast nicely. Then the oven finishes the job more gently than aggressive stovetop frying.
I prefer to add the garlic at the end, not at the beginning. Garlic burns faster than potatoes brown, especially in a hot pan. By adding butter, garlic, and parsley after the potatoes are roasted, the finish tastes fresh instead of bitter.
This recipe is more decorative than my air fryer baked potatoes and more hands-on than a rich French gratin dauphinois. It sits in its own place: small, golden, carved potatoes for when the side dish needs to look a little more special.
Ingredients You Need
Use small potatoes, preferably baby potatoes or creamer potatoes. The best size is about 1 ½ inches wide. If they are much smaller, they are annoying to carve. If they are too large, they lose the cute mushroom look and take longer to cook.
A mix of white, red, and purple potatoes looks beautiful, but one kind is fine. The red and purple skins make the mushroom caps stand out nicely after carving
The turmeric is optional. It gives the blanching water a slight golden color, but it is not there to make the potatoes taste like curry. Bay leaves are also simple, but they give that quiet restaurant-style aroma in the background.
For the fat, use neutral oil first, then butter at the end. The oil handles the heat. The butter gives the finish.
How to Shape the Potatoes
Hold one potato upright between your fingers. Imagine the top is the mushroom cap and the bottom will become the stem.
With a small sharp paring knife, make a shallow circular cut around the potato about one-third of the way down from the top. Do not cut all the way through. This is just the line that separates the cap from the stem.
Now peel the bottom part of the potato, starting below that circular cut. Remove thin strips of potato until a little stem appears. The top stays unpeeled. The bottom becomes narrower and rounded, like the stem of a small mushroom.
At this point, it should look like a tiny mushroom with a cap and a short foot. It does not need to be perfect. In fact, a slightly uneven stem often looks more natural.
As you carve them, place the potatoes in a bowl of cold water. Potatoes darken when they sit in the air, and the water keeps them clean and fresh-looking while you finish the batch.
The safest way is to go slowly. Turn the potato, not the knife, whenever possible. Use short cuts. A small paring knife gives better control than a big chef knife here. For more general knife prep, my guide on how to cut an onion cleanly and safely is a useful kitchen technique reference, even though this potato cut is more decorative.
Blanching the Potatoes
Bring a pot of salted water to a boil with turmeric and bay leaves. The water should be moving before the potatoes go in.
Add the carved potatoes and blanch them for 3 to 4 minutes. You are not trying to cook them all the way through. The outside should feel slightly softened, but the potatoes should still be firm enough to hold their shape.
Drain them carefully. I like to place them on a clean towel or in a bowl lined with a towel so the moisture can disappear quickly. Shake them gently, but do not smash them around. Those little stems are not made of iron.
You know they are ready for the pan when the surface looks matte instead of shiny-wet.
Roasting and Finishing
Heat a large oven-safe skillet with neutral oil. The oil should shimmer, but it should not smoke hard. If the oil is smoking, the pan is too hot and the flavor can turn harsh.
Add the potatoes in a single layer. They should sizzle lightly when they hit the pan. If they sit there quietly with no sound, the oil is not hot enough. If they spit violently, they were probably too wet.
Season with salt and pepper, then move the pan to a hot oven. I prefer 400°F because the potatoes roast more cleanly and develop better color than they do at 300°F. Stir them once halfway through if you can do it without breaking the shapes.
When they are cooked, they should be tender when pierced with the tip of a knife. The edges should have a light golden color, especially around the peeled stems.
Pour off excess oil. Add butter, finely chopped garlic, and parsley. The garlic should smell fragrant almost immediately. Stir gently for 30 to 60 seconds. The mistake to avoid is walking away here. Garlic can go from beautiful to burnt very quickly.
For a useful reference on that step, see my guide on how to mince garlic without burning it. It applies perfectly here because the garlic is added to an already-hot pan.
What to Serve with Mushroom-Shaped Potatoes
These potatoes are a side dish, so they work best beside something juicy, saucy, or roasted.
They are very good with a steak dinner, especially something like pan-seared steak bites with garlic butter or a bistro-style rib steak with mustard sauce. The little potato mushrooms look especially good on the plate with steak juices and a spoonful of sauce.
For fish, serve them with pan-seared salmon, lemon butter baked cod, or trout with brown butter and almonds. The potatoes are mild enough not to compete with the fish.
For chicken, I like them next to lemon garlic chicken thighs or a more classic chicken supreme. If the main dish has pan juices, even better. Potatoes like sauce.
If you want something fresh on the side, add a crisp salad such as red cabbage salad or cabbage and carrot salad with creamy dressing. The contrast helps because these potatoes are buttery and roasted.
Substitutions
Potatoes: Use baby potatoes, creamer potatoes, or small Yukon Gold potatoes. Red baby potatoes work very well because the skin makes a nice cap. Purple potatoes are beautiful but can be a little more delicate.
Turmeric: Leave it out if you do not have it. The recipe still works. A small pinch of paprika can be used, but it will change the flavor more than turmeric does.
Bay leaves: Fresh thyme or rosemary can replace the bay leaves in the blanching water, but keep it subtle. This potato side dish should not taste heavily perfumed.
Butter: Use salted or unsalted butter. If using salted butter, reduce the final salt slightly. Margarine can work, as in the original video, but butter gives a better flavor.
Garlic: Use one small clove for a mild finish or two cloves for more aroma. Garlic powder is not ideal here, but in a pinch, use a small pinch at the end with the butter.
Parsley: Chives, dill, or a little tarragon can work. Parsley is the most classic and the most neutral.
Oil: Use canola, vegetable, sunflower, avocado, or another neutral high-heat oil.
Tips for Best Results
Use potatoes that are close in size. When some are tiny and others are huge, the small ones can overcook before the big ones are tender.
Do not skip the cold water after carving. It keeps the potatoes from oxidizing and also rinses off some loose starch.
Dry the potatoes very well. This is not a small detail. Moisture is the enemy of browning.
Do not overcrowd the skillet. If the potatoes are stacked, they steam. Use two pans if needed.
Keep the garlic for the end. Burnt garlic is one of the fastest ways to ruin a good pan of potatoes.
Season twice if needed. A little salt in the blanching water and a little more after roasting gives better flavor than trying to fix everything at the table. My guide on how to season a recipe properly explains that idea in more detail.
FAQ
Can I make these potatoes ahead of time?
Yes, partly. You can carve the potatoes a few hours ahead and keep them in cold water in the refrigerator. Drain and dry them very well before blanching. I would not roast them too far ahead because they are best when served hot from the pan.
Can I use regular potatoes instead of baby potatoes?
Yes, but the final look changes. Larger potatoes are easier to practice on, but they do not look as elegant on the plate. If using regular potatoes, choose small ones and increase the roasting time as needed.
Why do my potato mushrooms break?
The circular cut was probably too deep, or the potatoes were stirred too roughly after blanching. Keep the cut shallow and use a gentle hand when moving them in the pan.
Why are my potatoes not browning?
The oven may be too low, the potatoes may be too wet, or the pan may be overcrowded. Use a hot oven, dry the potatoes well, and keep them in one layer.
Do I need to peel the whole potato?
No. The top should stay unpeeled because it becomes the mushroom cap. Only peel and trim the lower part to create the stem.
Are these potatoes crispy?
They are more roasted and golden than deeply crispy. Because they are blanched and carved, the goal is a tender potato with lightly browned edges, not a hard-crunch fried potato. For a more snack-style potato, homemade potato chips are a different kind of recipe entirely.
Can I make this in the air fryer?
It can work, but the shapes are delicate. Blanch and dry the potatoes, toss them gently with oil, then air fry at 375°F until tender and lightly browned. Shake the basket carefully. For a simpler air fryer potato side, use air fryer sweet potatoes or baked potatoes instead.
Is this a healthy recipe?
It is still a potato side dish cooked with oil and butter, so it is not a low-fat recipe. That said, the portion is easy to control, and it can fit beside lighter proteins like fish or chicken. The key is not drowning the finished potatoes in extra fat.
