How to Cut Your Grocery Bill in Half

1. Make A Budget 

This might not sound exciting, but it’s the foundation for saving money on groceries. Without a budget, it’s far too easy to overspend on things you don’t really need.

The good news? Budgeting doesn’t have to be complicated. I use this exact spreadsheet to track our monthly expenses.

Start by looking at your household income and essential expenses. Then, review your grocery spending from the last six months. Highlight what was essential (milk, bread, vegetables) and what was more of a luxury (snacks, takeaways, extra drinks). You might be surprised by how much those “just a little treat” purchases add up.

Next, work out the average amount you’ve spent on food each month. From there, set a realistic budget, ideally a little lower than your current average, and challenge yourself to stick to it. Track your spending weekly to keep yourself accountable.

Bonus tip: Take your grocery budget out in cash or move it into a separate bank account to keep track. When the money’s gone, it’s gone, and that’s a great motivator to shop wisely. We do this, and it’s been so helpful!

2. Plan Your Meals Like a Pro

Once you know your budget, the next step is to plan your meals. This is where the real savings happen. A good meal plan means you only buy what you need, waste less, and avoid those last-minute “let’s just get takeaways” nights.

Start by listing your family’s favourite meals, then check what’s in season and on special. If zucchini is pricey this week, swap it for a cheaper alternative, like carrots or frozen beans. Seasonal produce isn’t just more affordable, it’s fresher and tastier, too.

Think about your weekly schedule as well. If sports nights are hectic, plan for slow cooker meals, one-pan bakes, or even a big salad with leftover roast chicken. Save the more involved recipes for nights when you have extra time.

On quieter days, double up recipes like lasagna, meatballs, or soups so you can freeze the extras. Having a freezer stash of ready-to-heat meals will save you both money and stress when life gets busy.

Bonus tip: Keep a list of your “go-to” budget-friendly meals on the fridge or in a notebook. It makes planning each week so much quicker and stops you from feeling stuck for ideas.

3. Embrace a Little Less Variety

It might sound obvious, but cooking a completely different meal every night means buying a wider range of ingredients, which can add up fast. By simplifying your weekly menu, you can save both money and time.

Try planning a few repeat meals each week and buying those ingredients in bulk. Bulk buying is usually cheaper, and it means you’re using up everything you purchase instead of letting bits and pieces go to waste.

I often cook a double batch so we can enjoy the same meal twice. Leftovers are perfect for busy nights when you don’t feel like cooking from scratch, and they reheat beautifully for lunch the next day.

Some of our favourites are roasted vegetable couscous salad, cheesy baked rigatoni, and sheet pan chicken fajitas. In summer, I also love making large crustless quiches packed with whatever’s growing in the garden. These can be eaten warm, cold, or sliced up and frozen for later.

4. Buy What’s in Season (or Grow It Yourself)

One of the easiest ways to cut your grocery bill is to shop with the seasons. When fruits and vegetables are in season, they’re usually cheaper, fresher, and far more flavourful than imported produce.

Plan your meals around what’s abundant at the moment. For example, summer might mean grilled chicken with fresh salads, while autumn could be hearty soups and roast vegetables. This seasonal swap keeps meals interesting without blowing the budget.

To get a feel for what’s in season, keep an eye on the price per kilo at your local store or market. Over time, you’ll start to recognise when produce is at its cheapest, which is when you should enjoy it in abundance.

If you have the space, growing your own food is another fantastic money saver. Start with easy, high-yield crops like zucchini, lettuce, spring onions, radishes, spinach, and silverbeet. Even a few pots on a balcony can provide fresh greens for months.

Bonus tip: When seasonal produce is extra cheap, buy in bulk and freeze, bottle, or dehydrate it. That way, you can enjoy it later in the year without paying premium prices.

5. Don’t Overlook Frozen Produce

Frozen fruits and vegetables are a budget-friendly lifesaver, and I always keep a good stash in the freezer. Not only are they often cheaper than fresh, but they’re also picked and snap-frozen at peak ripeness, which means they lock in nutrients and flavour.

You can enjoy them year-round, even when they’re out of season. For example, frozen berries are perfect for smoothies in the middle of winter, and frozen corn or beans can turn a simple dinner into something colourful and nourishing.

Some of my freezer staples include:

• Corn
• Capsicum
• Beans and peas
• Berries (blueberries, strawberries, raspberries)
• Spinach
• Mango
• Carrots
• Onions

Frozen spinach is one of my favourites. Fresh spinach can be pricey, but the frozen version is much more affordable and just as versatile. I add it straight into smoothies, quiches, frittatas, stir-fries, scrambled eggs, or even pies.

Bonus tip: Keep a running list of your freezer stock on the fridge door so you know what you have at a glance. It’ll save you from buying doubles and help you plan meals around what’s already there.

6. Shop Locally and Support Your Community

Your local farmers’ market or produce stall can be a goldmine for fresh, affordable food. Not only are you supporting local growers, but you’re also often getting better quality produce for less than the big supermarkets.

Many small growers use minimal or no chemicals, pick their produce fresh, and sell unique varieties you won’t find in the standard supermarket aisles. Shopping this way can turn grocery buying into more of an experience, one where you can chat to the grower, learn how the produce was grown, and even pick up cooking tips.

7. Swap Brand Names for Budget-Friendly Alternatives

Brand loyalty can be expensive. While there’s nothing wrong with loving a particular product, many supermarket “house brands” or generic labels are just as good and often made by the same manufacturers.

Start by comparing the unit price (the cost per 100g/100ml or per ounce/fluid ounce) on the shelf label. You might be surprised at how much you can save by switching to a cheaper alternative.

You don’t have to change everything at once. Begin with a few easy swaps. For example, keep your favourite brand of coffee if it’s non-negotiable, but choose a budget peanut butter, pasta, or canned tomatoes instead. Over time, these small changes can add up to big savings.

8. Make Your Own Convenience Items

It can feel daunting at first, but making your own “convenience” foods and household products is one of the best ways to save money, reduce waste, and control what goes into the things you use every day.

Store-bought items often come with a higher price tag and a long list of additives you don’t really want. When you make them yourself, you can choose better ingredients, skip the nasties, and tailor recipes to your taste. Plus, it’s surprisingly satisfying to stock your pantry and fridge with things you’ve made from scratch.

Some of my favourite homemade swaps include:

• Soft Homemade Sandwich Bread – fresher, tastier, and cheaper than store-bought
• Soft Bread Machine Cheese Rolls – perfect for lunchboxes or alongside soup.
• Chocolate Chip Cookies – homemade is better, don’t even try to convince me otherwise!
• Old Fashioned Yeast Dinner Rolls Recipe – a family favourite for Sunday roasts.
• Creamy Condensed Milk Ice Cream – so creamy and endlessly customisable.
• Homemade Burger Patty Recipe – better flavour and no fillers.
• Homemade Granola – customise with your choice of nuts, seeds, and natural sweeteners.

And it’s not just food, you can also make your own hand soap, laundry liquid, or all-purpose cleaner using natural ingredients that are gentler on your skin and the environment.

9. Compare Prices by Weight, Not Just the Sticker Price

One of the easiest ways to shop smarter is to look at the price per weight (per 100g or per kilo or per ounce/pound if you’re in the US) rather than the total price. In New Zealand, this information is printed on supermarket shelf labels, and once you start using it, you’ll spot the better value option in seconds.

It’s tempting to grab the cheapest-looking item, but smaller packaging can sometimes mean you’re paying more for less. By comparing the unit price, you can quickly see which product gives you the most for your money.

This works especially well for fresh produce. Check if the pre-packaged bags are cheaper per kilo than buying loose items, or vice versa. Sometimes a 1kg/2lb bag of carrots will be a bargain, while other times the loose ones work out cheaper.

Bonus tip: Apply this habit beyond the fruit and veggie section. It works brilliantly for pantry staples like rice, flour, and pasta, as well as cleaning products and snacks.

10. Never Shop Hungry (or Try Shopping Online)

We’ve all been there, popping into the supermarket before dinner and suddenly finding our trolley filled with snacks we didn’t plan to buy. Shopping on an empty stomach makes it far too easy to give in to cravings and impulse buys.

The simplest fix? Eat before you shop. Even a quick snack, like a piece of fruit or a sandwich, can help you make more sensible, budget-friendly choices.

If you really want to avoid temptation, try doing your grocery shopping online. You can see your total as you go, making it easier to stick to your budget, and you’re less likely to be lured by in-store specials and end-of-aisle displays. Many supermarkets also let you save your favourite items for a faster checkout next time.

11. Use Up What You Already Have

Before you head to the shops, take a quick look at what’s in your fridge, freezer, and pantry. Planning meals around what you already have is one of the simplest ways to reduce waste and save money.

Keep an eye on ingredients that are close to their expiry date and make them the star of your next meal. If you can’t use something in time, pop it in the freezer to extend its life.

Get creative with leftovers by turning them into something new. Leftover roast vegetables can become a frittata, stir-fry, or soup. A few slices of cooked meat can be chopped into a salad, stirred through pasta, or turned into sandwiches for lunch.

Even scraps can be put to good use. Save vegetable offcuts in a freezer bag to make homemade vegetable or chicken bone broth. And if something truly can’t be eaten, compost it to feed your garden instead of filling the bin.

Bonus tip: Have a weekly “use it up” night where you make a meal entirely from what’s left in the fridge and pantry. We do this a lot, which I share on my YouTube channel!

12. Keep Your Pantry Stocked with the Basics

A well-stocked pantry is like a safety net! It means you can always pull together a quick, budget-friendly meal without rushing to the shops.

Focus on versatile staples that form the base of many recipes, such as:

• Flour and baking powder
• Rice, pasta, and oats
• Tinned tomatoes and beans
• Spices and dried herbs
• Cooking oils and vinegar
• Sweeteners like honey or sugar

With these on hand, you can create countless simple meals. For example, whip up corn fritters using frozen corn, flour, and baking powder, then serve with a side salad. Or make a batch of homemade granola with oats, honey, coconut oil, nuts, and seeds for an easy breakfast or snack.

To Sum Up

Saving money on groceries doesn’t have to mean sacrificing flavour, variety, or quality. With a little planning, a few small habit changes, and a more mindful approach to shopping, you can make a big difference to your weekly budget.

Even if you start with just one or two of these tips, you’ll soon see the savings add up, and that extra money can go towards something far more enjoyable than the supermarket bill.
