Super tender, juicy, fall-apart crock pot roast is not as hard as you think! This slow cooker recipe uses a few simple ingredients (one of them is patience) to make the most flavorful (yet stupid easy) pot roast ever! Carrots add the perfect touch! Originally posted January 18, 2018.

I don't know about you guys, but I kind of wanted to just skip January this year, and all the dumb kale diets that go with it. I'm having some serious December withdrawals. I kind of feel like December broke up with me and I wasn't ready for it. Now I'm dying my hair, "finding myself," my face is breaking out and all I want is Ben and Jerry's. Come on, December. We were so good together.

We're two weeks into the new year anyway, and that's usually about when my diet peters out, so I'm comin at you with some comfort food to numb the Christmas break up. POT ROAST AND MASHED POTATOES FOREVER.

Crock Pot Pot Roast

Pot Roast is a beef chuck roast that has been braised slowly with savory spices like garlic and onions. (If your grandma hasn't made this for you at least once, you need to get a new grandma. This is American comfort food at it's finest, especially when you pair it with Creamy Mashed Potatoes.)

Do you suck at making pot roast as much as I used to? You can be a great pot roast maker, you really can be. All it takes is a little patience and a packet of onion soup mix. (Those onion soup packets are pretty magical. I use them to make this 3 Ingredient Roasted Potatoes with Crunchy Onions, too. So good.)

Pot Roast Crock Pot Ingredients

Here's what you'll need at the store. (Quantities listed in recipe below.)

3-4 pound chuck roast
2 (1-ounce) packets of onion soup mix. If you have a smaller chuck roast, use 1 and ½ packets.
Carrots
Better Than Bouillon Beef Base. You can substitute regular beef broth if you want.
Dried thyme. For a fun variation, try oregano or Italian seasoning.
Bay leaf
Salt and pepper
Oil. Optional for browning.
Water

What is the best cut for making a Pot Roast in crock pot?

Chuck roast is where it's at. Chuck roast is a really tough cut of meat, but by the time it's done braising in the slow cooker for 8-10 hours, it has broken down into a beautiful, tender delight. You just need to wait.

Choose a chuck roast with lots of good marbling. The fat that runs throughout the meat melts while it's cooking, essentially self-basting the roast. Fat = flavor, so choosing a marbled roast is very important. After a very long cook time, the fat has mostly melted into the meat, making it super tender and flavorful.

How to make a Crockpot Pot Roast

Here's a basic overview. All instructions listed in the recipe below.

Choose a well-marbled roast with lots of white fat.
Brown the chuck roast in oil over medium high heat.
Place the roast in a crock pot along with pan juices.
Add spices and onion soup mix.
Cook on low for 8-10 hours.
Add carrots in the last 3 hours of cooking.

Why is my Crock Pot Chuck Roast tough?

I seriously used to be the worst at making pot roast so I used to ask myself that question all the time. They always came out kind of flavorless, or worse, so tough that you could barely chew through them. But since discovering the onion soup mix trick and the most important rule (waiting), I always get super tender, flavorful, juicy pot roasts.

Why should I cook my Pot Roast in a crock pot, rather than the oven?

Pot roast with onion soup mix in slow cooker

I love making pot roast in the slow cooker. It just seems so much easier to me than dealing with oven cooking, plus it's nice to be able to "set it and forget it." You know how most crock pot recipes you can cook either on low for 8 hours or on high for half the time? I don't recommend that for pot roast. Cooking at a higher temperature for a shorter time will result in rubbery meat that will make you feel like you're chewing on an old tire.

Is it better to cook a Roast on high or low in a crock pot?

You know how most crock pot recipes you can cook either on low for 8 hours or on high for half the time? I don't recommend that for pot roast. Cooking at a higher temperature for a shorter time will result in rubbery meat that will make you feel like you're chewing on an old tire. Chuck roast is a tough cut of meat and it needs plenty of time to break down into juicy, tender deliciousness.

Roast meat and carrots with mashed potatoes and gravy

Do you have to brown the meat before making Crockpot Pot Roast?

Short answer: no. I tested it both ways and it still tastes great so if you already started your roast or you don't have enough time when prepping your roast you'll still have great roast at the end of the day. However, I highly recommend browning the entire roast. It only takes a few minutes and adds a richness that can take your roast to the next level. Hey, if you're going to the trouble to make this thing you're probably trying to impress someone, right? You might as well take the extra step to make it amazing.

How much water do you put in a slow cooker when cooking a Roast?

I like to add beef broth to my pot roast instead of water. It's a great way to bring in that savory, beefy flavor. I love to use Better Than Bouillon Beef Base to make the broth.

You don't need much broth. Pot roast is meant to be braised, which means cooking meat slowly over low heat with minimal liquid, covered. If you add too much water/broth, you are going to miss out on that roasty flavor that comes from the top part of the meat cooking above the liquid. Because braising requires a lid, the moisture stays in the pot instead of evaporating, concentrating the liquid and tenderizing your chuck roast into melt-in-your-mouth glory.

Do you put vegetables on top or bottom of Pot Roast?

Vegetables should go on top. This recipe calls for the carrots to be added in the last 3-4 hours. Now listen here folks, I know it's annoying to have to come back and add the carrots later. You can totally add them in at the beginning with the roast if you like, but be prepared for overcooked, mushy, and in my opinion, flavorless carrots. They will add nothing to your dinner besides some orange color, because they will have been cooked for 6 hours too long. Those poor carrots! Do yourself a favor and add the carrots later, or cook them separately.

The same goes for potatoes in my opinion. If you want to add them, put them in (cut into chunks) with the carrots. But really what you ought to do is leave the potatoes out of the slow cooker entirely. Make my Aunt Shirley's Famous Creamy Mashed Potatoes instead. I'm pretty sure this is the way God intended pot roast to be eaten.

Don't skip the gravy

What's a pot roast without a little somethin somethin? This gravy takes about 5 minutes to make and will really take your pot roast up a notch.

The Drippings from the crock pot are on the left. I like to use a fat separator so that I'm making my gravy with only broth, no fat.

Better Than Bouillon is my favorite beef base. This is what I use to make the broth for the gravy (in addition to drippings). It's affordable, it has better flavor than any other broth I've tried, and I can keep it on hand in the fridge.

Whisk together a little water and flour, making sure to get out all the lumps before slowly pouring it into your simmering broth/drippings.

And voila! Perfect pot roast, with plenty of gravy to go around. If your grandma really hasn't ever made you pot roast, don't worry, you don't need to get a new one. Just make her this recipe and establish your reign as the pot roast ruler in your family!

The Easiest Fall-Apart Pot Roast in Crock Pot (Slow Cooker)

Servings: 6 Servings

Prep Time: 10 mins

Cook Time: 10 hrs

Total Time: 20 hrs 10 mins

Super tender, juicy, fall-apart pot roast is not as hard as you think! This slow cooker recipe uses a few simple ingredients (one of them is patience…) to make the most flavorful (yet stupid easy) pot roast ever! Carrots add the perfect touch!

For the roast

3 to 4 pound chuck roast, *
salt and pepper, copious amounts, copious I say!
1 tablespoon oil, optional (for browning)
1 & 1/2 cups water
1 & 1/2 teaspoons Better Than Bouillon Beef Base, **
1/2 teaspoon dried thyme
1 bay leaf
2 1-oz packets onion soup mix
2 pounds carrots, peeled and chopped into chunks

For the gravy

2-3 cups of drippings from the meat
1-2 cups COLD water
1/3 to 1/2 cup flour
2 teaspoons Better Than Bouillon Beef Base
2 tablespoons butter, optional
salt and pepper to taste

First you are going to have to make a choice about whether you want a really good roast, or a really REALLY good roast. Browning the meat before slow cooking makes it extra special. To do that:

Heat a wide skillet over medium high heat. Generously salt and pepper all sides of the roast. I would say I use somewhere between 1 and 1/2 to 2 teaspoons kosher salt, and about a teaspoon of pepper.
Add 1 tablespoon oil to the hot pan and swirl around to coat the bottom. It should be shimmery right away if your pan is hot enough.
Add the roast to the pan and don't move it for about 1-2 minutes. Check to make sure it is nice and brown, then flip it over and repeat on the other side. Brown every side of your roast that you can. It should not take more than 5-6 minutes.
Transfer the roast to your slow cooker (6 quart or larger).
Keep the hot pan on the stove and add the water and beef base. Stir, breaking up any brown bits on the pan, until the beef base is dissolved. Pour the liquid into the slow cooker.
Sprinkle the roast with the dried thyme or add the fresh thyme. (Just throw the sprig in the pot)
Add the bay leaf.
Dump the 2 packets of onion soup mix directly on the roast (not in the water). Use your hand to rub the dry powder into the part of the roast that is exposed. Some of it will just fall off into the water, and that's fine.
Cover with the lid and set to low heat. Cook for 8-10 hours. If you are a bit short on time, you can turn the slow cooker on to "high" for one hour to get things boiling, then turn back down to low. I do NOT recommend cooking this on high for 4-5 hours. You can if you want, it will be cooked, but it will not be as tender!
If you are not browning the meat, it's so easy. Salt and pepper the meat, rub on the thyme and onion soup mix, and place in a slow cooker. You don't need the oil. Add all the other ingredients, set it on low, and you're done!
Add the carrots: about 3 hours before you want to eat, add the peeled and chopped carrots. See photos, they don't need to be tiny pieces, I tend to like the bigger chunks myself.
When the meat is fork tender and easy to shred, carefully remove it to a cutting board and let rest for a couple minutes. Then shred with two forks or slice with a serrated knife against the grain. Transfer the roast and the carrots to a serving platter and keep warm. (Taste a carrot to see if it needs salt and pepper)
To make the gravy: Use a fat separator to get the fat from the top of the drippings. Discard fat and add the drippings to a medium saucepan. Turn the heat to high. (Use all of the drippings that you have, up to 3 cups. You want about 4 cups of liquid going into your gravy, and at least one cup needs to be COLD water to dissolve the flour.)
In a measuring cup, whisk together 1-2 cups COLD water (or beef stock, if you're not using beef base) with the flour. Make sure you get rid of all the lumps.
When the drippings have heated to a boil, slowly stir in the flour mixture while stirring. Add the beef base and bring the mixture to a low boil.
Let the gravy simmer for 3-5 minutes until it has thickened.
At this point you can add the butter if you want. It's not necessary, but it does add some richness that I love. Season with salt and pepper. Make sure you taste it first!
Devour, preferably with these Famous Creamy Mashed Potatoes. To die for!!

*Meat options: For this recipe you can use a chuck roast, boneless chuck roast, chuck shoulder pot roast, etc. Look for good marbling!

**You can omit the water and beef base and just add 1 and 1/2 cups good quality beef stock instead! This goes for the gravy too. (The ratio is 1 teaspoon of base per cup of water.) This is not a sponsored post, I just love how easy it is to keep beef base on hand in the fridge.
