Ingredients
• For the Family Pot Roast
• 3-4 lb (1814 g) beef chuck roast
• 1 lb (454 g) carrots, roughly chopped
• 1 large onion, quartered
• 2 lbs potatoes, quartered
• 8 oz (226.8 g) mushrooms, whole or halved
• 1 cup water or beef broth
• Salt and black pepper, to taste
• For the Individual Keto Serving
• 43 g / 1.5 oz heavy cream
• 23 g / 0.8 oz cooked beef chuck roast
• 12 g / 0.4 oz cooked carrots
• 10.7 g / 2 tsp European-style butter
• 11 g (0.39 oz) / 2 tsp walnut oil
Instructions
1. Preheat your oven to 325°F (165°C).
2. Place the beef chuck, carrots, onion, potato, and mushrooms into a large roasting pan or Dutch oven.
3. Pour the water or broth into the bottom of the pan, just enough to cover it. Season generously with salt and pepper.
4. Cover the pan tightly with a lid or heavy-duty foil and cook for 4 hours.
5. Remove the cover and continue to cook for 1 more hour, allowing the meat and vegetables to brown nicely.
6. Remove the roast from the oven. Before seasoning the main dish further, use a gram scale to carefully weigh out your keto portion: 23 g (0.81 oz) of cooked beef and 12 g (0.42 oz) of cooked carrots.
7. Season the remaining pot roast in the pan to your family’s preference with additional herbs, spices, or salt.
8. To complete your keto meal, place your weighed beef and carrots in a small dish and top with the butter, allowing it to melt over the warm food.
9. Mix the heavy cream with a small amount of water to create a keto-friendly “milk” to drink. Serve the walnut oil in a small cup to drink alongside your meal.
Nutritional Information
• Dietitian’s Corner
• Walnut oil is a fantastic source of polyunsaturated fatty acids (PUFAs), particularly omega-3s. These healthy fats are known to support heart health by helping to lower blood cholesterol levels.
Pro Tips
• For a deeper, richer flavor, sear the beef chuck roast on all sides in a hot, oiled skillet before placing it in the roasting pan.
• Use the leftover pan drippings from the family’s portion to create a delicious gravy. Simply whisk in a bit of flour or a cornstarch slurry and simmer until thickened.
• Feel free to add other low-carb vegetables like celery or radishes to the main roast. Just be sure to weigh them accurately for your keto portion.
• This recipe is great for meal prep! The keto portions can be pre-weighed and stored in separate containers for easy grab-and-go meals throughout the week.
FAQ
Q: What is the best cut of beef for this pot roast
A: A 3-4 lb (1814 g) beef chuck roast is ideal for this recipe because its marbling and connective tissue break down during slow cooking, resulting in incredibly tender, fall-apart meat. Brisket or a round roast can also be used as alternatives.
Q: Can I make this pot roast in a slow cooker
A: Absolutely. To adapt this for a slow cooker, place all the family roast ingredients inside and cook on low for 8-10 hours or on high for 4-5 hours, until the beef is tender. You can sear the roast beforehand for extra flavor.
Q: How can I make the entire pot roast keto friendly
A: To make the whole dish keto, simply omit the potatoes and carrots. You can replace them with more low-carb vegetables like celery, radishes, or green beans to ensure the pan is still full.
Q: Why are the keto portion ingredients weighed so precisely
A: The keto portion is weighed in grams to ensure accurate macronutrient tracking, which is essential for maintaining a state of ketosis. This precision allows for exact control over your carb, fat, and protein intake for that specific meal.
Pro Tips
- Sear the chuck roast on all sides in a hot, oiled skillet before it goes into the roasting pan — the browned crust adds a deeper, richer flavor to the whole dish.
- Weigh your keto portion (23 g cooked beef, 12 g cooked carrots) on a gram scale before the family's seasoning goes in, so the macros stay exact.
- Extra low-carb vegetables like celery or radishes can join the main roast — just weigh them accurately when you build your own plate.
- Use the family's pan drippings for their gravy, and keep yours simple: the butter, cream, and walnut oil are the fat layer for your keto serving.
- This is ideal meal prep — pre-weigh the keto portions into separate containers and grab one all week long.
Frequently Asked Questions
Can I meal-prep the keto pot roast portions?
That's exactly what this recipe is built for — weigh the cooked beef and carrots into separate containers and refrigerate. Add the butter and cream fresh when reheating.
Is this pot roast keto if it's cooked with potatoes?
Yes — the potatoes are for everyone else. Your keto serving is the weighed beef and carrots only, landing at 2 g of carbs and 42 g of fat.
Why is the walnut oil served separately?
It's drunk alongside the meal as part of the fat macros — a source of polyunsaturated omega-3 fats that keeps the keto portion high-fat without changing the roast itself.
Can I cook the roast in a slow cooker instead?
Yes — sear the beef first, then slow-cook with the broth and vegetables until tender. Weigh your keto portion the same way once everything is cooked.
