Pistachio Crusted Roast, with Carrots and Potatoes – Lesson 7: One Pot Meal Pressure Cooker Pot Roast

You’ve never had a one pot meal that is this as elegant! The pistachio and fresh thyme crust make this beef roast exciting to both the eyes and taste buds. The sauce is made from the beef’s own juices, a jus, the whole meal can be ready in about 45 minutes – versus making a roast in the oven in 2 to 2.5 hours!While carrots only take 2 minutes and potatoes 10 to cook under pressure, you can cook them both in 5 using a little trick that I will teach you – plus a few more!
One Pot Meals in the Pressure Cooker
A one pot meal, as the name says, is an entire meal (that includes vegetables, starch and protein) made in one cooking vessel. There are several techniques to make one pot meals in the pressure cooker. Some dishes, likes stews ad roasts, naturally lend themselves to the addition of vegetables during cooking, while others need accessories, tin foil or little helping hand.
Stack-it. Using trivets and small additional containers or steamer baskets (see my heat-proof container and steamer basket suggestions), you can cook a meat dish on the bottom of the pressure cooker, and then stack on a steamer basket or additional container to cook rice or vegetable. Unlike an oven, the hottest part of the pressure cooker is at the bottom because of the direct contact with the metal which is closer to the heat source . Longer-cooking foods always go on the bottom. Then, work your way up the stacks to finish with vegetables at the top which, with the exception of the potatoes, always need very little heat and time to cook!
Phase it. Use ingredients with different cooking times by phasing them into the pressure cooker one at a time. Start with the longest-cooking ingredient first (usually meat or a legume), then, when it is getting closer to the cooking time of the next ingredient, bring down the pressure, open the pressure cooker to add the next ingredient. You can do this several times and even cook the last ingredient without the pressure cooking top (like adding pasta or cooking dumplings).
Wrap it! Using al Cartoccio, or packet cooking, you can actually wrap a whole meal in a packet and cook it by steaming it in your pressure cooker. Also, tin foil can be used to slow down the cooking of ingredients that usually take less time, as Lorna Sass does this in her Reader Recipe on Triplex Cooking.
Re-size it. The size, density and thickness of a food, will dictate how long it will take to cook in the pressure cooker. Use this information to your advantage when crafting a one pot meal. For example, in the instructional recipe below, I was able to cook carrots (which only need 2 minutes at high pressure) and potatoes (which need 10 minutes at high pressure) together in just 5 minutes. I simply used thick carrots and cooked them whole, while the potatoes were sliced down to a large cubes.
Recipe it. All gimmicks aside, some recipes are natural one pot meals and do not need any tricks special techniques. Recipes like chowders, chilies, soups, stews, risotto and packet cooking (links to specific recipes for most of these, below) naturally have almost all of the food groups required for a one pot meal, or can be easily served with a nice thick slice of bread.

Lovely recipe. Would be perfect for Valentines Day which is also my 24th wedding anniversary! I have almost 5 lbs of almonds. Any suggestions?
Yum! I love the pistachio crust.
Beautiful! Awesome photos, and amazingly tasty meal!! Lovee it!:)
Hi Kitty, congratulations! I thought of promoting the roast as a romantic way to leave you free for other activities but you know.. it’s difficult to make a roast sound romantic!
5 lbs of almonds!!! I love it. I just saw a program on raw food where the lady soaked the almonds overnight, blanched them for about 1 minute (for the peels to come off) cooled them and then blended them with enough water to make it the raight consistency, strained and — fresh almond milk! Made my mouth water!!! She also had a great segment on sprouting legumes and eating them raw! It all sounds so exotic and new to me – though I have been curious about sprouting since I heart it makes legumes cook faster (though you spend 3-5 days sprouting them!) Ooops, totally off-topic now.
Happy Anniversary!
Briarose and Sandra, thank you for your kind comments.

why not use a few of the almonds for the crust? Maybe with a little honey! The rest
I’m allergic to pistachios — is there something else I could use to encrust this roast? Would crushed almonds or walnuts or pecans work as well?
Hi Gayle, you can leave them out completely. Though walnuts and almonds sound like a fantastic substitution!

What size pressure cooker do you have, use, or suggest?
Mariah,
You can see all of my pressure cooker shopping tips, under the tab “go shopping” at the top of this page.
For the photographed recipes on this website, and my family of 4, I primarily use 6L /6.34qt – on occasion I use a large wide pressure braiser, or a small pressure pan.
For the most versatility, I recommend a 6L pressure cooker – and if you can afford it to get a set with a second smaller base that will fit the same pressure cooking top.
Once you get really good at pressure cooking, and move ALL your wet cooking (steaming, braising, boiling) to the pressure cooker you may find that even the pressure cooker set is not enough. At that point, I recommend investing in a nice wide braiser pressure cooker.
But for just staring out a 6L will be the most versatile size.
Ciao,

Lots of food in the pressure cooker = longer to reach pressure.
It’s quicker when you are adding food later to cook for the last few minutes in the already-hot pressure cooker, but it still takes longer to reach pressure when the pan has more food (up to 2/3 its interior height). The time to reach pressure increases more when you add frozen food e.g. frozen peas.
I thought I’d let readers know that the pressure cooker can be closed and on high heat with the food and liquid, but appear to be doing nothing except releasing more and more steam from the coloured pressure indicator, until suddenly it rises and the pressure builds. This can take as long as 10 – 15 minutes if you have lots of food! This assumes: the lid is closed properly, the pan rim is not dented, the gasket is not defective, the heat is on high and the pressure setting is selected.
Apologies for the long-winded message, but it’s something I have learned when pressure cooking lots of food compared to a small amount.
