The Kitchn published a six-ingredient Instant Pot mac and cheese recipe by culinary producer Kelli Foster. It uses a short high-pressure cook, a five-minute natural pressure release and three cheeses; the recipe says the dish takes about 25 minutes overall and serves six to eight.
The Kitchn has published a six-ingredient recipe for Instant Pot mac and cheese, by culinary producer Kelli Foster, that cooks the pasta under high pressure and finishes it with cream cheese, sharp cheddar, fontina and half-and-half or whole milk. The recipe is listed as serving six to eight people and taking about 25 minutes overall, offering home cooks a relatively quick pressure-cooker version of a familiar meal.
The ingredient list names dried elbow macaroni, water, kosher salt and butter, alongside the three cheeses and dairy used at the end. The recipe calls for four ounces of cream cheese, eight ounces of sharp cheddar, four ounces of fontina, and three-quarters of a cup plus two tablespoons of half-and-half or whole milk. Foster recommends half-and-half for a richer result, while the recipe says whole milk can be used instead.
For the pressure-cooking step, the directions put the water and salt in a six-quart or larger electric pressure cooker, then add the macaroni in an even layer without stirring and scatter butter over it. The cooker is set to high pressure for two minutes. The recipe estimates roughly 10 minutes for the appliance to reach pressure, a time that helps explain why the two-minute cook setting is not the same as the total cooking time.
After cooking, the directions call for a five-minute natural pressure release, followed by a quick release of the remaining pressure. The pasta is then loosened before the cheeses and dairy are added. The pot is covered for two minutes so residual heat can soften the cheese; the cook then stirs again until the mixture is smooth and creamy. Kitchn says leftovers can be stored in an airtight container in the refrigerator for up to four days and reheated with a splash of milk.
A Short Pressure-Cooker Route to Dinner
The recipe’s main practical appeal is its combination of a brief active cooking process and a modest ingredient list. Pressure cooking the pasta in the same appliance used to finish the sauce avoids a separate roux-making step, according to the recipe’s description. That makes the method relevant to cooks seeking a straightforward meal for a family or small group, rather than a development in the appliance market or a change to established food guidance.
The details also matter for setting expectations. The pasta cooks for only two minutes once the cooker reaches pressure, but the appliance needs time to pressurize and the finished dish needs a short rest for the cheese to melt. The recipe’s 25-minute estimate includes more than the programmed pressure-cooking time. Its stated yield of six to eight and four-day leftover guidance may also help readers decide whether to make it for one meal or prepare portions to refrigerate.
Foster emphasizes fontina as part of the recipe’s flavor and melting profile, while sharp cheddar supplies a stronger cheddar taste than mild or medium varieties. Those are the recipe author’s recommendations, not independently tested comparisons in the supplied source. Readers should also note that the dish contains milk and wheat: dairy appears in the cheeses, butter and milk or half-and-half, while elbow macaroni is typically wheat-based. Check product labels for specific allergen information.

How the Recipe Uses Pressure
This report is a recipe publication rather than an announcement of a new Instant Pot model or a broader change in cooking advice. The source identifies Foster as a recipe developer and food writer with more than 10 years of professional experience, and credits her with developing the dish for Kitchn. It does not provide outside testing data or comparisons with other pressure-cooker recipes.
The method depends on the sequence after pressure cooking. Kitchn advises against stirring the dry pasta in the pot before sealing it, saying excess stirring can cause clumping or a gummy texture. It also recommends waiting five minutes before releasing the remaining pressure. According to the recipe, an immediate release can cause starchy water to sputter from the valve; the short natural release also lets residual heat continue cooking the pasta.
The cheeses are added after the pressure stage, not cooked under pressure with the macaroni. The recipe directs cooks to let the covered pot sit for two minutes after adding dairy and cheese, then stir. That approach is intended to use the pasta’s residual heat to melt the cheese and limit over-stirring, which the author says can make the result stringy.

Recipe Timing and Results Vary
The supplied source gives a total estimate of 25 minutes, while its detailed directions say the cooker takes about 10 minutes to reach pressure, followed by a two-minute high-pressure cook and a five-minute natural release. It does not separately itemize time for grating cheese, releasing the remaining pressure, or mixing and resting the finished dish. Actual total time may vary by appliance and preparation pace; the source provides no independent timing test.
The source does not report reader testing, nutritional information, a cost per serving, or how results compare across Instant Pot models. It specifies a six-quart-or-larger electric pressure cooker, so it does not establish whether the same quantities or timing work in smaller appliances or other pressure-cooker designs. It also does not provide a dairy-free or gluten-free variation. Its texture and flavor descriptions are the recipe author’s characterization rather than a guarantee for every cook.
Follow the Published Cooking Steps
The source presents a complete recipe rather than announcing a later launch, test, or update. Readers who make it can follow the stated order: cook the macaroni at high pressure for two minutes, wait five minutes before releasing the remaining pressure, then add the dairy and cheese and let the covered mixture rest for two minutes. The recipe’s next practical step for leftovers is to refrigerate them in an airtight container for no more than four days and add a splash of milk when reheating.
No follow-up testing or revision is announced in the supplied report. Any future changes to the recipe, reader feedback or additional guidance would need to come from Kitchn or the recipe author; the source does not say that such updates are scheduled.
Key Questions
How long does the Instant Pot mac and cheese take?
Kitchn lists the recipe as taking about 25 minutes overall. Its detailed directions estimate about 10 minutes for the cooker to reach pressure, followed by a two-minute high-pressure cook and a five-minute natural release, plus preparation and finishing time.
How many people does the recipe serve?
The recipe lists a yield of six to eight servings. The source does not give a serving weight or specify portion sizes.
Can I use whole milk instead of half-and-half?
Yes. The recipe allows whole milk or half-and-half and says half-and-half makes the dish richer and creamier. It calls for three-quarters of a cup plus two tablespoons.
Why wait before releasing the pressure?
Kitchn advises a five-minute natural release before quick-releasing the remaining pressure. The recipe says an immediate release can cause starchy water to sputter from the steam valve, while the brief wait lets residual heat continue cooking the pasta.
How should leftovers be stored and reheated?
Store leftovers in an airtight container in the refrigerator for up to four days, according to the recipe. Reheat with a splash of milk to loosen the sauce. The dish contains dairy and wheat-based pasta, so people avoiding those ingredients should check labels and choose suitable alternatives; the source does not provide a tested substitute recipe.
