What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to create a rich, satisfying meal that’s sure to impress. Here’s what you’ll need:

• Beef Chuck Roast: 3-4 lbs, trimmed of excess fat (this cut is perfect for slow cooking).
• Salt and Pepper: To season the beef before searing.
• Olive Oil: For searing the beef to lock in flavor.
• Garlic: 6 cloves, minced (for both the roast and mashed potatoes).
• Onion: 1 large, sliced.
• Carrots: 4 large, peeled and cut into chunks.
• Potatoes: 2 lbs of Yukon Gold, peeled and quartered.
• Beef Broth: 2 cups (low-sodium is ideal).
• Red Wine: 1 cup (optional but highly recommended for depth of flavor).
• Bay Leaves: 2 whole.
• Fresh Thyme: 4 sprigs.
• Butter: 1/2 cup, softened (for the mashed potatoes).
• Heavy Cream: 1/4 cup (adds richness to the potatoes).
• Parsley: 2 tbsp, chopped (optional garnish).

These ingredients are easy to find and versatile—you probably have most of them in your kitchen already. If you need substitutions, I’ll cover that in the variations section below.

Equipment Needed

Here’s what you’ll need to make this recipe:

• Slow Cooker: Essential for achieving that perfect tender beef.
• Large Skillet: For searing the roast before slow cooking.
• Tongs: Useful for flipping the beef while searing.
• Potato Masher: To get the perfect creamy consistency for the mashed potatoes.
• Cutting Board: A sturdy one for prepping veggies and meat.
• Chef’s Knife: Sharp enough to chop your ingredients effortlessly.
• Mixing Bowl: For combining the mashed potato ingredients.

If you don’t have a slow cooker, a Dutch oven works wonderfully as a substitute—just keep an eye on the oven temperature and cooking time.

Preparation Method

1. Season and Sear: Pat the beef chuck roast dry with paper towels. Generously season both sides with salt and pepper. Heat olive oil in a large skillet over medium-high heat, then sear the roast for 3-4 minutes per side until browned. Set aside.
2. Prepare the Vegetables: Slice the onion and chop the carrots into chunks. Mince the garlic cloves.
3. Layer in the Slow Cooker: Place the sliced onion and chopped carrots at the bottom of your slow cooker. Lay the seared beef on top.
4. Add Flavor: Pour beef broth and red wine over the roast and vegetables. Add minced garlic, bay leaves, and thyme.
5. Cook Low and Slow: Cover the slow cooker and set to low heat for 8-10 hours (or high heat for 4-5 hours). The beef should be fork-tender when done.
6. Prepare the Mashed Potatoes: About 30 minutes before the roast is ready, boil the peeled and quartered potatoes in salted water until fork-tender (about 20 minutes). Drain and return to the pot.
7. Mash and Season: Mash the potatoes with softened butter, heavy cream, minced garlic, salt, and pepper until smooth. Stir in chopped parsley for a fresh touch.
8. Serve: Remove the beef from the slow cooker and shred or slice as desired. Serve alongside the garlic herb mashed potatoes and the cooked vegetables, garnished with fresh parsley.

Pro Tip: For extra flavor, strain and reduce the cooking liquid from the slow cooker into a luscious gravy to drizzle over the roast and potatoes!

Cooking Tips & Techniques

• Searing is Key: Don’t skip searing the beef before slow cooking—it locks in flavor and creates a beautiful caramelized crust.
• Low and Slow: Cooking on low heat ensures tender, juicy meat that practically falls apart.
• Don’t Overmix the Potatoes: Mash gently to avoid gummy mashed potatoes—overworking them can ruin the texture.
• Using Fresh Herbs: Fresh thyme and parsley elevate the dish, but dried herbs work in a pinch.
• Adjusting Liquid Levels: If your slow cooker tends to lose liquid, keep an eye on it and add a bit more broth as needed.

These tips are tried and tested—you’ll end up with a pot roast and mashed potatoes that taste like they took way more effort than they actually did!

Variations & Adaptations

• Gluten-Free Option: Skip the red wine or use gluten-free broth if needed.
• Low-Carb Twist: Swap the potatoes for mashed cauliflower with garlic and cream.
• Vegetarian Version: Replace the beef with hearty chunks of portobello mushrooms and use vegetable broth instead of beef broth.

Feel free to experiment with different herbs or vegetables—parsnips, celery root, or sweet potatoes all make great additions to this recipe. Once, I added a splash of balsamic vinegar to the cooking liquid for a tangy twist, and it was a hit!

Serving & Storage Suggestions

This dish is best served hot, straight from the slow cooker. Pair it with a side of crusty bread or a glass of red wine for the ultimate cozy meal. Here’s how to store the leftovers:

• Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days.
• Freezing: Freeze the beef and mashed potatoes in separate containers for up to 3 months.
• Reheating: Warm the beef in the slow cooker on low heat or in the oven at 300°F (150°C). Microwave the mashed potatoes in short bursts, stirring frequently.

The flavors deepen with time, so don’t be surprised if the leftovers taste even better the next day!
