Step 1: Brown the Beef - Begin by heating a heavy-bottomed skillet over medium-high heat. Add the chuck roast and sear it for about 4-5 minutes on each side, until it forms a rich, golden-brown crust.

Step 2: Layer Vegetables - In your slow cooker, start by placing the heartier vegetables like chopped onions and carrots at the bottom. Next, lay the browned beef on top, followed by slices of zucchini and halved cherry tomatoes.

Step 3: Add Liquid & Season - Pour in your choice of broth or crushed tomatoes, about one cup, sprinkle in fresh herbs, minced garlic and a splash of red wine vinegar.

Step 4: Cook - Cover the slow cooker and set it to low heat for 7–8 hours or high for 4–5 hours until the beef becomes fork-tender.

Step 5: Finish and Serve - Check the beef for tenderness; shred with a fork. Optionally broil with cheese or croutons on top until golden.

Step 6: Enjoy the Aromas - Pair with a crisp salad or grilled vegetables.
