Why this stew works for keto
Leg of lamb delivers about 20 g protein and 10 g fat per 100 g of raw meat, leaner than the shoulder but rich in flavor. 220 g of leg of lamb per serving brings around 38 g protein and 19 g fat from the meat alone. The missing fat comes from butter (15 g in the puree) and cream (50 ml), which together add about 30 g of fat. Celery root has roughly 2.4 g net carbs per 100 g, making it moderately keto friendly; 80 g per serving adds about 2 g net carbs. Cauliflower comes in at around 3 g net carbs per 100 g; 200 g in the puree per serving adds about 6 g net carbs, the biggest carb contributor after the braising liquid. Overall, the dish lands at about 7 g net carbs, 52 g fat and 46 g protein for around 750 kcal.

Cauliflower puree instead of mashed potatoes
Classic mashed potatoes (200 g per serving) deliver around 28 g net carbs, enough on their own to blow a strict keto daily limit. Cauliflower puree (200 g per serving) has about 6 g net carbs, less than a quarter of that. The flavor is milder than potato, so feel free to be generous with butter and a pinch of nutmeg.

Leg of lamb vs. lamb shoulder for stew
Lamb shoulder has more connective tissue and fat; after 90 minutes of braising it turns creamy and tender. Leg of lamb is leaner and needs a little less time; it does not fall apart as much and keeps its cubed shape. For a classic braised stew, leg works very well as long as the sauce is enriched with butter, which balances out the lower fat content.
How do I serve and vary this lamb stew?
Spoon the puree onto a deep plate, press a well into it with the back of a spoon and ladle the stew with plenty of sauce on top. From my own experience, the cauliflower puree turns out creamiest when the cauliflower is steamed rather than boiled, otherwise it picks up water that you would later have to compensate for with extra butter.
Meal prep: storing and reheating
The stew keeps for 3 days in the fridge and up to 3 months frozen. Cauliflower puree keeps for 2 days and turns creamy again when reheated with a splash of cream. Reheat gently in a saucepan; the microwave makes the puree grainy. When freezing, freeze the puree separately.
If you would rather skip the red wine
Replace 150 ml of red wine with 150 ml of extra beef broth plus 1 tsp of apple cider or balsamic vinegar. The sauce will have less body but stays aromatic. For an alcohol-free variation with more depth, use 50 ml of soy sauce in the braising liquid; it adds only about 1 g net carbs but plenty of umami.
What tips help with keto lamb stew and cauliflower puree?
- Cut the leg of lamb into 3 cm cubes, smaller ones fall apart during the long braise.
- Cut celery root into 1 cm cubes so it can braise along without disintegrating.
- Steam the cauliflower instead of boiling it, otherwise the puree turns watery.
- Blend the puree for at least 2 minutes in a high-speed blender for a silky texture.
- Reduce the sauce uncovered for the final 15 minutes, no flour needed, body comes from reduction.

FAQ
Is cauliflower puree keto friendly?
Yes, very much so. Cauliflower has about 3 g net carbs per 100 g, a quarter of what potatoes deliver. Whipped with butter and cream it takes on a silky texture and adds extra fat, which fits the ketogenic profile perfectly.
How do I get the cauliflower puree extra creamy?
Three steps: 1) Cut the cauliflower into small florets and steam (do not boil) until tender. 2) Drain it well or dry it off briefly over high heat. 3) Blend in a high-speed blender for at least 2 minutes with butter and cream, do not use a masher, which never delivers a silky finish.
Can I make this stew in the slow cooker?
Yes. Sear the meat in a pan, then transfer it with the wine, broth and celery root to the slow cooker and cook for 5 hours on low or 3 hours on high. If needed, reduce the sauce separately in a pot at the end. Make the puree fresh, it does not hold up well to long warming.
Does this stew fit into a keto weight-loss plan?
Yes: 46 g of protein keep you full for hours, and the 7 g of net carbs fit comfortably into a daily ketogenic budget of around 20 g. If you want to cut calories, reduce the butter in the puree to 10 g and the cream to 30 ml, which brings the serving down to about 620 kcal with 44 g of protein.
