The Solo Stove Pi Prime, model PIZZA-OVEN-PRIME, is a round propane pizza oven. It comes from a company better known for fire pits. One 15,000 BTU burner fires from the back of a domed chamber. A thin pie bakes in about 90 seconds.
That speed sounds like the whole story, and it is not. One rear flame and no thermometer means the cook finishes the job. So the real question is simple. How much of that 90 second bake do you supply yourself?
The answer decides who should own one. For some cooks it will feel like a chore. For others it becomes the best part of Friday night.
First Impressions of the Solo Stove Pi Prime
Out of the box, the Pi Prime looks like kitchen hardware, not camping gear. The drum is brushed 304 stainless, about 20.5 in across. A dark perforated band wraps the base. One black knob sits dead centre on the front.
There is almost nothing to assemble. The two halves of the cordierite stone drop onto the chamber floor. Thread the hose onto a propane tank, and that is it.
Your eye goes straight to the mouth, which Solo Stove calls panoramic. It spans 13 in. It is also low, at just 3.5 in.
As a result, sliding a pie through it feels almost forgiving. Peeking at the underside feels cramped by comparison.
Lighting takes one twist and a spark or two. Orange flame rises behind the stone and licks under the dome. The first pizza came out blistered on top and charred beneath. One side was darker than the other, and that is the oven’s first lesson.
The size tells you what kind of evening to expect. Each bake is a single pie of 12 in or less. A family of four eats in shifts, with the cook on duty throughout. Nobody sits down until the last pizza leaves the stone.
Key Features of the Solo Stove Pi Prime
Start with the burner’s address, at the very back. The burner is fixed at the rear. The curved roof throws its heat forward, which Solo Stove calls demi-dome heating. Almost every item below answers to that rear flame.
- Single rear burner, 15,000 BTU. One flame, one valve, one knob. That is plenty for a 12 in oven, and very directional.
- Demi-dome roof. The ceiling bends heat from the back wall toward the front of the stone. It narrows the front-to-back gap without closing it.
- Panoramic opening, 13 x 3.5 in. A wide, flat slot. Launching is easy, and peel work stays comfortable.
- Two-piece cordierite stone, 13 mm. Halves weigh less than one slab and clean more easily. Their joint runs under the pie.
- Spark ignition in the knob. Turn it and the burner catches. No matches needed.
- Stainless steel. The outer drum and trim are 304 stainless. Rain bothers it far less than painted steel.
- Cover. Some retailers pack a fitted Pi Prime Shelter in the box. Check the listing before counting on one.
What it lacks matters too. There is no built-in thermometer and no door. Nor are there tall legs to lift it to working height. Each absence hands a little more work back to the cook.
The Pi Prime gets very hot, very quickly. It passes 900°F in about 15 minutes. A pie then bakes in a 750-degree chamber in 90 seconds. Listings rate the top end at 950°F, while Solo Stove’s own gallery art says 900°F.
Either figure puts Neapolitan style well within reach. The catch is direction. The rim nearest the wall blisters while the rim by the mouth stays blond. Leave a pie alone and it comes out burnt behind, pale in front.
The fix is a turn about halfway, and often a second one. That is why a turning peel, sold separately, starts to feel essential.
Recovery between pizzas is strong, because the chamber is small and the burner is fierce. After several pies it can even run too hot. A slight turn of the knob settles it.
Going the other way is slow. Falling from 900°F to 550°F takes about 20 minutes, even on the lowest setting. That is a long wait for a New York pie. In practice, plan one style per evening.
The stone itself does its job well. Cordierite holds its stored heat well, so the underside chars in step with the top. The bottom rarely lags the top here.
Here, the problem is the back edge, never the base. Learn the turn, and the results stay consistent.
Build, handling and durability
The build feels solid where it counts. The 304 stainless drum resists rust, and a round body has no thin corners to dent. At 30 lb, one adult can lift it into a car. Listings print 15.5 in for height, though the gallery art says 15.125 in.
Trouble starts on the outside of the drum. The shell gets very hot during a bake, the top worst of all. It stays hot for more than an hour after shutdown. That matters on a crowded patio, and more with children around.
The hose is the other gripe. It is short, so the tank must sit right beside the table. On a picnic table that works fine. Otherwise durability looks good, since one burner and one valve leave little to fail.
Portability is real, with limits. Setup is a hose, a tank and a flat surface. Set it on a tailgate or a camp table and light it. But plan where it cools, because it cannot ride home hot.
Running costs, upkeep and value
Running costs are modest. Flat out, the burner uses roughly 1 lb of propane per hour. That works out to under $1 an hour.
You supply the 20 lb tank, since none comes with the oven. A tank that already feeds your grill will do, provided it reaches the short hose.
Upkeep is light, because propane burns without ash. A damp cloth handles the drum after it cools. The stone needs the most care, because cordierite stains for good. Scrape off loose crumbs and burnt flour first, then wash gently.
Value is where the price drift shows. The Pi Prime launched at $349. Today the Amazon listing reads around $399.99, captured on 2026-10-15. At that number you get a lifetime warranty and a tidy stainless shell.
You do not get a turning peel or an infrared thermometer. This oven really wants both, so the true entry price climbs. The lifetime warranty is the strongest reason to pay it anyway. It covers manufacturing defects for as long as you own the oven.
A stand is the last question, and Solo Stove’s own is not cheap. A sturdy outdoor table does the job well enough. Pick one that can take a hot base. Keep its top clear around the oven.
Possible Solo Stove Pi Prime Complaints
- Uneven bake from the rear flame. The back of every pie browns first. Look away for a moment and the crust can blacken. A mid-bake turn solves it, but only if you stand there.
- No way to read the stone. Solo Stove fits no gauge, so an infrared gun becomes your second purchase. Until then, perfect and scorched arrive seconds apart.
