Slow-Cooker Lamb and Lentil Soup for Iron and Energy
Share
It's dark by five, the heating's on, and the last thing you want after a long day is to stand over a stove. You're tired in a way that sleep doesn't quite fix, and what you're craving is something warm, substantial, and genuinely nourishing, not another sad bowl of toast.
This soup is the answer to exactly that evening. You load the slow cooker in the morning, get on with your day, and come home to a deeply savoury pot of lamb, lentils, and greens. It's hearty, it freezes beautifully, and it happens to be packed with three nutrients that matter during this stage of life: iron, zinc, and protein.
It isn't a cure for tiredness, and no single meal could be. But what's on your plate genuinely shapes how you feel, and this one earns its place on a cold winter night.
Why Iron, Zinc, and Protein Matter More During Menopause
The link between these three nutrients and how you feel day to day is bigger than most of us were ever told. Here's why they deserve a regular spot on your plate.
Iron and the tiredness that sleep won't fix
Iron helps your blood carry oxygen around your body, which is part of why low iron so often shows up as fatigue, breathlessness, or that foggy, flat feeling that no amount of rest seems to shift. It's one of the most common and most overlooked reasons women feel exhausted.
Perimenopause is a particularly vulnerable window. As your cycle becomes unpredictable, periods can get heavier or closer together, and that ongoing blood loss can quietly drain your iron stores over months. If you've been running on empty, it's worth asking your GP for a simple blood test rather than guessing, because iron is one thing you don't want to over-supplement without knowing your levels. Eating iron-rich foods like the lamb and lentils in this soup is a gentle, everyday way to support your stores through the foods you already enjoy.
Zinc, the quiet multitasker
Zinc plays a role in immune function, skin repair, taste, and the everyday hormone metabolism happening in the background of your body. It's a mineral many of us don't get quite enough of, and red meat and legumes are two of the richest dietary sources, which makes this soup a generous double dose.
Protein for the strength you want to keep
As oestrogen declines, the body finds it harder to build and hold onto muscle, which is why protein becomes more important, not less, in midlife. A protein-rich meal also keeps you fuller for longer and helps steady your energy between meals. Between the lamb and the lentils, this bowl delivers a satisfying hit of it in every spoonful.
If steady energy is something you're chasing more often than you'd like, you might find our guide on regaining your energy during menopause a useful companion read.
The Recipe: Slow-Cooker Lamb and Lentil Soup
Serves: 6 | Prep: 15 minutes | Cook: 7–8 hours (low) or 4 hours (high)
This is a true set-and-forget meal. There's an optional five-minute browning step that deepens the flavour, but if you're short on time you can skip it and simply add everything to the pot. The leftovers are arguably better the next day.
What you'll need
For the soup:
- 1 tbsp olive oil
- 500g diced lamb shoulder (or 2 to 3 lamb shanks)
- 1 large brown onion, diced
- 3 garlic cloves, finely chopped
- 2 carrots, diced
- 2 celery stalks, diced
- 2 tsp ground cumin
- 1 tsp ground coriander
- 1 tsp smoked paprika
- 1 cup (200g) dried brown or green lentils, rinsed
- 1 x 400g tin crushed tomatoes
- 1.5 litres beef or chicken stock
- 1 bay leaf
- Sea salt and black pepper, to taste
To finish:
- 2 large handfuls baby spinach or chopped kale
- Juice of half a lemon
- Fresh parsley, to serve
How to make it
A few notes before you start
- No slow cooker? This works on the stovetop too. Brown the lamb and aromatics in a heavy pot, add the remaining soup ingredients, then simmer gently with the lid on for around 1.5 hours until the lamb is tender.
- Batch and freeze: The soup freezes well for up to three months. Portion it out once cooled and you've got a head start on next month's busy nights.
- Make the iron count: The tomatoes and finishing lemon aren't just for flavour. Their vitamin C helps your body absorb more of the plant-based iron from the lentils, so don't skip them.
- Prefer it meat-free? Leave out the lamb, double the lentils, and add a tin of chickpeas. You'll lose the easily absorbed iron from the lamb, so pair the bowl with a vitamin C-rich side to help your body make the most of the plant iron.
Why each ingredient earns its place
Lamb brings the most easily absorbed form of iron, along with zinc, B12, and protein, making it the nutritional backbone of the bowl. Lentils add plant-based iron, more protein, and a good dose of fibre, which supports digestion and gut health, a topic worth its own read in our piece on fibre during menopause.
The tomatoes and the squeeze of lemon are doing quiet but clever work here. The vitamin C they contain helps your body absorb the plant-based iron from the lentils far more effectively, so finishing with lemon isn't just for brightness. The leafy greens stir in extra iron, folate, and antioxidants right at the end, keeping their goodness intact.
Beyond the Bowl
One good meal is a lovely start, and a few small habits alongside it can make the difference feel more lasting. A handful of simple things that tend to help:
- Pair iron with vitamin C: Citrus, capsicum, and tomatoes alongside iron-rich foods help your body absorb more of the iron, just like the lemon does in this soup.
- Mind your timing: Try to keep strong tea and coffee away from your iron-rich meals, as they can blunt absorption when taken at the same time.
- Spread your protein out: Build a little into every meal, not just dinner, to help maintain muscle and keep your energy steadier through the day.
For some women, food and rest go a long way, and fatigue still lingers. If that sounds familiar, our Energy blend may help support vitality and ease the mental and physical tiredness that menopause can bring, with adaptogens like Siberian ginseng and ashwagandha.
So when the evenings draw in and your energy dips, let dinner do some of the heavy lifting. Load the pot in the morning, get on with your day, and come home to something warm, restorative, and quietly working in your favour.
