Equipment Needed

How to Make It
-
1
Prepare the Ingredients
Peel and dice potatoes into 1-inch cubes, slice carrots into ½-inch rounds, finely chop the onion, and mince the garlic. If using a chuck roast, trim excess fat and cut into uniform 1-inch cubes for even cooking. This mise en place ensures a smooth assembly process.
-
2
Brown the Beef (Optional but Recommended)
Heat a tablespoon of olive oil in a large skillet over medium-high heat. Sear the beef in a single layer — don’t overcrowd — for 2–3 minutes per side until nicely browned. Work in batches if needed. This caramelization adds significant depth of flavor to your finished casserole.
-
3
Layer the Slow Cooker
Start by layering the chopped vegetables (potatoes, carrots, onion, garlic) at the bottom of the slow cooker — this creates a protective layer and allows them to cook gently in the broth. Place the beef evenly on top. Pour in the gluten-free beef broth and add all seasonings: salt, pepper, thyme, paprika, and the bay leaf. Gently stir to combine.

4
Cook
Cover and cook on Low for 7–8 hours for melt-in-your-mouth tenderness, or on High for 4–5 hours if time is short. The casserole is ready when the beef is fork-tender and the vegetables are soft. Avoid lifting the lid during cooking — each peek adds about 20 minutes to the cook time.
-
5
Thicken the Sauce
During the last 30 minutes, whisk together 2 tablespoons of cornstarch (or arrowroot) with 2 tablespoons of cold water to form a smooth slurry. Stir it into the hot casserole. Replace the lid and cook on High for another 30 minutes, until the sauce is rich, glossy, and clings beautifully to the beef and vegetables. Remove the bay leaf before serving.
Tips for the Best Casserole
- Choose well-marbled beef for tenderness: Opt for stew meat or chuck roast with visible streaks of fat — this renders down during slow cooking, keeping the meat moist and incredibly tender. Leaner cuts can become dry.
- Don’t overfill the slow cooker: Fill no more than two-thirds full for even cooking and proper temperature throughout — this affects both texture and food safety.
- Cut vegetables evenly: Uniform sizing is crucial so everything finishes cooking at the same time — no mushy pieces or undercooked chunks.
- Always check broth labels: Many commercial broths contain hidden gluten. Look for products explicitly labeled “gluten-free” or “certified gluten-free” to avoid cross-contamination.
Variations
Dairy-Free
This recipe is naturally dairy-free. All core ingredients are free from dairy. When serving with mashed potatoes, simply use a dairy-free milk alternative and vegan butter.
Low-Carb / Keto
Replace potatoes with cauliflower florets added during the last hour of cooking. Increase non-starchy vegetables like bell peppers or zucchini for extra volume without the carbs.
Vegetable-Loaded
Add zucchini or green beans in the last hour, or stir in fresh spinach during the final 15 minutes. Parsnips, turnips, or sweet potatoes also work beautifully.
Serving Suggestions
A classic pairing — creamy mashed potatoes are perfect for soaking up the rich gravy. Use plant-based milk for a dairy-free option.
A slice of warm, crusty gluten-free bread is ideal for mopping up every last drop of the delicious sauce.
Simple white or brown rice offers a neutral base that complements the robust flavors and stretches the meal further.
A light salad with vinaigrette dressing cuts through the richness and adds a refreshing balance of textures.

Either methodFrequently Asked Questions
Can I skip browning the beef?
Yes — the casserole will still be delicious. Browning adds a deeper, richer flavor through caramelization, but if you’re short on time, simply add the raw beef cubes directly to the slow cooker.
Can I make this in an Instant Pot?
Absolutely. Use the sauté function to brown the beef, then add all ingredients. Cook on High pressure for 30–35 minutes, followed by a 10–15 minute natural pressure release. Thicken the sauce using the sauté function afterwards.
How do I know if my broth is gluten-free?
Always read the ingredient label carefully. Look for certifications like “gluten-free” or “certified gluten-free.” Hidden sources can include hydrolyzed wheat protein, wheat starch, or maltodextrin derived from wheat. When in doubt, opt for brands that state gluten-free explicitly.
Can I use ground beef instead?
Yes, though the texture will differ. Brown the ground beef in a skillet first, drain excess fat, then add to the slow cooker. The result will be more crumbly than a traditional stew-style casserole, and the cooking time may be slightly shorter.
