Instant Pot Slow Cook Roast Recipe: Dual-Method Fall-Apart Beef

This dual-method roast delivers fall-apart beef whether you use an Instant Pot or slow cooker. The secret lies in the initial sear, which locks in juices and builds deep flavor foundations.

Both methods yield tender, succulent meat with rich gravy, but the Instant Pot cuts cooking time dramatically while maintaining quality. The slow cooker offers hands-off convenience for busy schedules.

You’ll achieve perfectly cooked beef with vegetables that absorb the savory broth. The result is a hearty meal that tastes like it simmered all day, even when using the faster method.

Ideal for Sunday dinners or weeknight meals when time is limited. This approach ensures consistent, professional-quality results every time.

Ingredients for Instant Pot Slow Cook Roast

Professional-quality ingredients for fall-apart beef with rich, savory depth in every bite.

The beef chuck roast is non-negotiable here. Costco offers excellent marbling at a good price point, but Whole Foods has premium grass-fed options if you’re splurging. Look for cuts with visible fat streaks—this renders down during cooking, creating that luxurious mouthfeel. The vegetables should be fresh but needn’t be organic (the good stuff, not the pre-cut kind).

No red wine? Additional beef broth with a splash of balsamic vinegar provides similar acidity. Dried herbs can be substituted with fresh at triple the amount, though the flavor profile will be slightly different. For the broth, Better Than Bouillon makes a robust beef base—just dissolve in hot water. The tomato paste can be omitted in a pinch, but the depth of flavor will suffer.

Store raw beef in the coldest part of the refrigerator for up to 3 days. The vegetables keep 1 week in crisper drawers. Leftovers freeze beautifully for 3 months—portion before freezing for easy reheating. Always bring meat to room temperature before searing for even cooking.

Step-by-Step Instructions for Instant Pot Slow Cook Roast

This dual-method approach ensures a perfectly tender roast with deep, developed flavors.

Step 1: Sear the Beef Chuck Roast

Pat the 3 lb Beef Chuck Roast dry with paper towels, then season generously with the 1.5 tsp Kosher Salt and 1 tsp Freshly Ground Black Pepper. This step is crucial—moisture prevents proper browning, and seasoning now ensures flavor penetration throughout the cooking process.

Set your Instant Pot to the sauté function and add the 2 tbsp Olive Oil. Once the oil shimmers, sear the roast on all sides until deeply browned, about 4-5 minutes per side. You’re looking for a rich, caramelized crust that will enhance the dish’s depth of flavor.

Step 2: Sauté the Aromatics

Remove the roast and set it aside. In the same pot, add the 2 whole Yellow Onions, 4 whole Carrots, 3 whole Celery Stalks, and 6 cloves Garlic Cloves. Sauté for 4-5 minutes until the onions soften and begin to develop a slight caramelization.

Add the 1 tsp Dried Thyme, 1 tsp Dried Rosemary, and 2 whole Bay Leaves, stirring to release their aromatic oils. Next, pour in the 2 tbsp Tomato Paste and cook for 1-2 minutes, stirring constantly to prevent burning. This step builds the flavor foundation for your gravy.

Step 3: Deglaze and Pressure Cook

Pour in the 0.5 cup Red Wine to deglaze the pot, scraping up all the browned bits from the bottom. These bits, known as fond, are packed with flavor and will dissolve into the liquid, enriching your sauce. Let the wine simmer for 2-3 minutes until reduced by half.

Return the roast to the pot and add the 2 cups Beef Broth. Secure the lid and set the Instant Pot to high pressure for 60 minutes. Once the cooking cycle completes, allow the pressure to release naturally for 15 minutes, then quick-release any remaining pressure.

Step 4: Slow Cook to Perfection

Carefully remove the roast and transfer it to a slow cooker. Pour the cooking liquid from the Instant Pot over the roast, ensuring all the vegetables and herbs are included. Set the slow cooker to low and cook for an additional 4-6 hours, or until the beef is fork-tender and falls apart easily.

This dual-method approach combines the efficiency of pressure cooking with the tenderness of slow cooking. The result is a roast that’s both rich in flavor and melt-in-your-mouth tender.

Step 5: Thicken the Gravy and Serve

Remove the roast and vegetables from the slow cooker and set them aside. Skim any excess fat from the surface of the cooking liquid. In a small bowl, whisk the 2 tbsp All-Purpose Flour with ¼ cup of the cooking liquid to create a slurry.

Stir the slurry back into the slow cooker and cook on high for 10-15 minutes, stirring occasionally, until the gravy thickens to your desired consistency. Serve the roast and vegetables with the gravy spooned over the top.

Essential Equipment for instant pot slow cook roast

Instant Pot Essentials

For this recipe, I recommend a 6-quart Instant Pot Duo—it’s the perfect size for a 3 lb roast with room for vegetables. The Duo model has all the functions you need, including sauté and pressure cooking. Look for models with a stainless steel inner pot for even heat distribution. 💪

Slow Cooker Choice

A 6-7 quart programmable slow cooker works best for the second phase. I use the Crock-Pot Touchscreen model with a 24-hour timer and auto-warm setting. Ceramic inserts are ideal for even heat retention. Avoid older models without temperature control.

Searing Tools

Since you start on the stovetop, use a wooden or silicone spoon to avoid scratching your Instant Pot’s non-stick surface. A tongs set helps flip the roast during searing. I keep a splatter screen nearby to contain oil splatters during the browning process.

Measuring and Prep

Accurate measurements matter here. I use OXO Good Grips measuring spoons and cups for the herbs and liquids. A fine-mesh strainer helps when skimming fat from the gravy. For prep, a sharp chef’s knife makes quick work of the vegetables.

Optional Upgrades

A fat separator simplifies gravy skimming, though a spoon works in a pinch. An instant-read thermometer ensures perfect doneness—203°F is ideal for fall-apart tenderness. I also love a gravy boat for elegant serving. ✨
