- Pat the beef dry with paper towels.
- Season with salt and black pepper.
- Sprinkle the flour over the beef and toss until evenly coated.
Step 2: Brown the Beef
- Heat the olive oil in a large skillet over medium-high heat.
- Brown the beef in batches for 2–3 minutes per side until nicely caramelized.
- Transfer the browned beef to the slow cooker.
This step adds extra flavor but may be skipped if you’re short on time.
Step 3: Add the Vegetables
Add the chopped onion, carrots, celery, swede (or parsnip), and crushed garlic to the slow cooker with the beef.
Step 4: Make the Sauce
In a bowl or measuring jug, whisk together:
- Beef stock
- Tomato purée
- Worcestershire sauce
Pour the mixture evenly over the beef and vegetables.
Add the bay leaves and thyme, if using.
Step 5: Slow Cook
- Low: Cook for 8 hours
- High: Cook for 4–5 hours
The beef should become fork-tender, and the vegetables should be soft while holding their shape.
Step 6: Thicken the Gravy (Optional)
For a richer, thicker casserole:
- Stir together the cornstarch and cold water until smooth.
- Mix it into the casserole during the final 20–30 minutes of cooking.
- Cook on High until the gravy thickens.
Step 7: Serve
- Remove the bay leaves before serving.
- Taste and adjust the seasoning with extra salt and pepper if needed.
- Garnish with fresh parsley.
Serve with:
- Creamy mashed potatoes
- Buttered crusty bread
- Steamed green beans
- Buttered peas
- Fluffy ric
Tips for the Best Beef and Vegetable Casserole
- Stewing beef or beef chuck becomes wonderfully tender during slow cooking.
- Browning the beef first creates a deeper, richer flavor.
- Add mushrooms, peas, or baby potatoes during the last hour for extra vegetables.
- Leftovers taste even better the next day as the flavors continue to develop.
- Store in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months.
