Step‑by‑Step Instructions for Cooked SUMMER Beef Casserole

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. This step is essential to lock in the flavors for your Cooked SUMMER Beef Casserole.

Step 2: Layer Vegetables
In your slow cooker, start by placing the heartier vegetables like chopped onions and carrots at the bottom. Next, carefully lay the browned beef on top, followed by slices of zucchini and halved cherry tomatoes. This layering technique ensures even cooking and flavor distribution in your casserole.

Step 3: Add Liquid & Season
Pour in your choice of broth or crushed tomatoes, which should be about one cup, ensuring not to overwhelm the dish with liquid. Next, sprinkle in a generous amount of fresh herbs, like basil and oregano, along with minced garlic and a splash of red wine vinegar. This mixture will infuse delicious flavors into your Cooked SUMMER Beef Casserole.

Step 4: Cook
Cover the slow cooker and set it to low heat for 7–8 hours or high for 4–5 hours. The goal is to cook until the beef becomes fork-tender and easily pulls apart. Resist the temptation to lift the lid during cooking; keeping it sealed preserves moisture and flavor.

Step 5: Finish and Serve
Once cooking is complete, check the beef for tenderness. It should easily shred with a fork. For added texture, if desired, transfer the casserole to a baking dish, top it with cheese or croutons, and briefly broil it until golden. This step adds a crispy touch to your Cooked SUMMER Beef Casserole, making it even more delightful.

Step 6: Enjoy the Aromas
As the casserole finishes cooking, let the heavenly aromas fill your kitchen. When ready to serve, pair it with a crisp salad or grilled vegetables to complement this light yet satisfying dish, making every meal a celebration of summer flavors.
