The Easiest 3 Ingredient Crock Pot Roast Ever! (Slowcooker)

I can still remember the comforting aroma that filled my grandmother’s kitchen every Sunday. It was the unmistakable scent of pot roast, slow-cooked to tender perfection. While her recipe involved a laundry list of ingredients and a meticulous browning process, I’ve discovered a shortcut that delivers nearly identical results with a fraction of the effort. This 3-ingredient wonder is my go-to when I crave that classic Sunday supper without spending all day in the kitchen.

Recipe Overview

• Prep Time: 5 minutes
• Cook Time: 8 hours
• Total Time: 8 hours 5 minutes
• Servings: 12
• Yield: 1 roast
• Dietary Type: Typically not vegetarian or vegan due to meat content

Ingredients

• 3 lbs pot roast (use the cheapest cut of beef you can find)
• ¾ ounce onion soup mix
• 2 tablespoons prepared yellow mustard (more or less to taste)

Optional Gravy

• 2 tablespoons cornstarch
• 4 tablespoons water

Equipment Needed

• Large Crock Pot (Slow Cooker)
• Saucepan (for optional gravy)
• Whisk (for optional gravy)

Instructions

1. Place the pot roast in a large crock pot. This will be the foundation of our incredibly easy meal.
2. Using a spoon or your hands, squirt or spread a thin layer of yellow mustard over the entire surface of the roast. Don’t be shy, but don’t overdo it either; a thin coating is all you need.
3. Evenly sprinkle the onion soup mix on top of the mustard-covered roast. Ensure all sides are generously coated with the dry mix.
4. Cover the crock pot and cook on low for 8 hours. If your roast is frozen, you can cook it on high for 8 hours instead. Resist the temptation to peek; the magic happens slowly and steadily.
5. Once the roast has cooked for the designated time, check for doneness. It should be incredibly tender and easily shredded with a fork.

Optional Gravy Instructions

1. Carefully strain the fat off the liquid from the crock pot and discard the fat. This step is crucial for a healthier and more appealing gravy.
2. Pour the reserved liquid into a saucepan and bring to a slight boil over medium heat.
3. In a small bowl, add cornstarch to the water and make a paste. Mix thoroughly until there are no lumps.
4. Slowly add the cornstarch paste to the boiling liquid, constantly whisking until the gravy begins to thicken. Continue whisking until the gravy reaches your desired consistency.
5. Serve the gravy immediately over the pot roast and accompanying sides.

Important Note: Do not add water to the crock pot at the beginning of the cooking process. Believe it or not, the roast will create its own liquid, resulting in a beautifully braised and flavorful dish. Adding water can effectively steam the roast, potentially making it tougher.

Expert Tips & Tricks

• Sear for Extra Flavor: While this recipe is all about simplicity, searing the roast in a hot skillet before placing it in the crock pot will add an extra layer of flavor complexity. Just sear each side for 2-3 minutes until browned.
• Adjust Mustard to Taste: Not a fan of yellow mustard? Try Dijon mustard or even a touch of horseradish for a different flavor profile.
• Herb Infusion: For a more nuanced flavor, tuck a few sprigs of fresh rosemary or thyme under the roast before cooking.
• Deglaze the Pan (if searing): If you choose to sear the roast first, don’t discard those flavorful browned bits in the pan! Deglaze the pan with a splash of red wine or beef broth, scraping up the browned bits, and then pour this liquid into the crock pot.
• Shred it for Sandwiches: If you end up with more roast than you can eat in one sitting, shred it and use it for delicious pulled beef sandwiches.

Serving & Storage Suggestions

Serve this incredibly tender pot roast hot, straight from the crock pot, alongside your favorite sides. Mashed potatoes, roasted vegetables (carrots, potatoes, and onions are classics), and a simple green salad are all excellent choices. The optional gravy adds a luscious finishing touch.

Storage:

• Room Temperature: Do not leave cooked pot roast at room temperature for more than 2 hours.
• Refrigerator: Store leftover pot roast in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: For longer storage, freeze the pot roast in an airtight container or freezer bag for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Reheating:

• Stovetop: Reheat the pot roast in a saucepan over medium heat, adding a little beef broth or water to prevent it from drying out.
• Microwave: Reheat individual portions in the microwave on high for 1-2 minutes, or until heated through.
• Oven: For larger portions, reheat in a baking dish in a preheated oven at 325°F (160°C) until heated through.

• Root Vegetables: Add a medley of root vegetables like parsnips, turnips, and sweet potatoes to the crock pot for a heartier meal.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of beef?
A: Absolutely! While a cheaper cut like chuck roast works best due to its higher fat content, you can also use a brisket or round roast. Just be sure to adjust the cooking time accordingly.

Q: Can I add vegetables at the beginning of the cooking process?
A: You can, but they might become overly soft. For best results, add hearty vegetables like carrots and potatoes about 2-3 hours before the end of the cooking time.

Q: Can I skip the searing step?
A: Yes, you can absolutely skip the searing step. This recipe is designed for simplicity, and the roast will still be incredibly tender and flavorful without searing.

Q: Can I make this in an Instant Pot?
A: Yes, you can adapt this recipe for the Instant Pot. Sear the roast first, then add the remaining ingredients and cook on high pressure for about 60-75 minutes, followed by a natural pressure release.

Q: Can I use low-sodium onion soup mix?
A: Yes, using low-sodium onion soup mix is a great way to reduce the sodium content of the dish. You may want to add a pinch of salt to taste at the end of the cooking process.
