Roast Beef with a beautifully creamy mustard dressing: it looks like your Sundays are sorted! I love my chef’s knife (and sharpen my baby daily), BUT in cases like this, I dig out my electric carving knife. I am not entirely sure why: maybe because it makes me feel like I am living in the 80’s but it is a little more accurate and will ensure that everyone gets a decent, even-sized slice (or two or three) of the good stuff… Check out the Side Dish ideas to serve alongside.

Fats of Life® is a blog I run as a hobby. I love spending time on it, but did you know that I am also the author of two best-selling cookbooks? KETO KITCHEN (2020) and LAZY KETO KITCHEN (2021) – both available worldwide and very well-priced. I have a third book on the way: BUDGET KETO KITCHEN, (coming mid-2022).
Perhaps its time to start building up your Keto Kitchen collection if you have not already done so. Not only will my books make beautiful Christmas stocking fillers for loved ones interested in a low carb lifestyle, but you could simply treat YOURSELF! Your family (whether they live keto or not) will not be disappointed with all your exciting, delicious creations!

Roast Beef with Creamy Mustard Sauce
- 1.3 kg (2.9 lb) beef roasting joint
- salt and freshly ground black pepper
- 150 g (5.3 oz) double cream
- 30 g (1.1 oz) sour cream
- 50 g (1.8 oz) hot English mustard
- Preheat the oven to 170°C (fan oven). This is 190°C for conventional ovens (or 375°F / gas mark 5).
- Season the beef on all sides with salt and freshly ground black pepper. Place into a small, deep roasting tray and wrap the entire tray very well with foil, ensuring its air-tight.
- Place in the oven for 90 minutes. (NOTE: If your joint is smaller or larger than mine, simply follow the basic rule: cook for 6 minutes for every 100g / 3.5oz of the beef's weight indicated on the packaging).
- When done, remove the beef from the tray and set aside on a tray and wrap again in a clean sheet of foil and set aside to rest.
- Tip all the juices from the tray (there will likely be a lot) into a pan and reduce by half over a high heat.
- Once reduced, add the cream, sour cream and mustard. Whisk well to combine and reduce to low heat, allowing the sauce to simmer gently and reduce further. If it curdles or looks like it is 'splitting', use a hand blender to bring it together.
- Keep your eye on the sauce, as it can boil over while you are sipping your Sunday tipple and not paying attention...
- Allow the sauce to reduce to a thick consistency. It should coat the back of a spoon. Set aside to keep warm.
- At this time, the beef would have rested for at least 15-20 min (perfect). To serve, snip away any string or twine (if you bought it like that) and slice it thinly (or thickly: no rules!) using a good quality knife. (I have an amazing chef knife which I sharpen daily, but for roasts like this, I always use my electric carving knife).
- Serve with the deliciously rich sauce and your favourite vegetables (search SIDE DISHES on the site for fantastic keto veg ideas, many include keto Yorkshire puddings and other great options!)
