Shopping for one can feel weirdly expensive. Family-size packs are cheaper per ounce but go bad before you finish them, single-serve packs cost more, and takeout starts to look easier than cooking for just you. The good news: saving money on groceries for one person is mostly about buying the right amounts and using everything you buy. You don't need to cut out every treat.

This guide covers the habits that make the biggest difference, a sample $40 weekly grocery list, and single-serving meal-prep ideas so nothing ends up in the trash.

Quick answer

The easiest way to save money on groceries for one person is to plan 3 or 4 meals that share ingredients, buy staples that keep (rice, oats, eggs, beans, frozen vegetables), use your freezer like a second pantry, and cook small batches you can split into single portions. Shop at a discount grocer, choose store brands, and buy fresh produce in small amounts you'll actually finish that week.

Why groceries cost more when you shop for one

It's not in your head. Most packaging is sized for families, so a solo shopper either pays more per unit for small packs or buys big packs and throws part away. Recipes usually serve four. And when you're tired, there's nobody else to cook, so eating out wins more often.

The fix isn't buying less. It's buying smarter and wasting less. Food you throw away is money you threw away, and for a lot of solo shoppers, cutting waste saves more than any coupon.

12 ways to save money on groceries for one person

1. Plan 3–4 meals, not 7

Cooking a different dinner every night is how single people end up with half-used jars everywhere. Plan three or four meals for the week, cook each one for two or three servings, and eat the leftovers. That covers lunches and dinners with far less shopping.

2. Pick ingredients that work in more than one meal

Before you add something to your list, ask: "Where else will I use this?" A bunch of cilantro can go into tacos, rice bowls and eggs. A bag of spinach can go into pasta, omelets and smoothies. If an ingredient only fits one recipe, swap it for one that fits more.

3. Make the freezer your best friend

Your freezer stops food from going bad before you can eat it. Freeze bread and use it slice by slice, split chicken into single portions before freezing, and freeze cooked rice, chili and soup in single-serving containers. Frozen vegetables and fruit cost less than fresh in many stores and never wilt in the drawer.

4. Buy staples in bulk, fresh food in small amounts

Big bags of rice, oats, dried beans and pasta keep for months, so buying in bulk saves money. Fresh produce, dairy and bread are the opposite: buy only what you'll finish in about 5 days. Loose produce lets you buy one onion or two bananas instead of a whole bag.

5. Shop at a discount grocer and buy store brands

Aldi, Walmart, WinCo, Lidl and Save A Lot often charge less than traditional supermarkets for the basics. Store brands like Great Value (Walmart), Good & Gather (Target) and Aldi's own labels are usually cheaper than name brands and fine for staples like canned tomatoes, flour, beans and frozen veg.

6. Check the unit price, not just the sticker price

The small shelf label showing the price per ounce or per pound tells you what something really costs. Bigger is usually cheaper per unit, but not always, and it's only a deal if you'll use it before it spoils. If you like an app to help with the comparing, the Nexus Grocery Pro app in Nexus Rewards #ad (free account to explore, full benefits $9.95/month) is one option; Nexus says it helps you make smarter decisions wherever you shop.

7. Use the deli and bulk bins

Need two slices of cheese or a quarter-cup of walnuts for one recipe? The deli counter and bulk bins let you buy exactly that. It costs more per pound, but much less than buying a whole pack and throwing half away.

8. Eat what you have before you shop

Once a week, do a quick "use it up" night: an omelet, fried rice, a quesadilla or a pasta toss with whatever's left in the fridge. Then shop only for the gaps.

9. Keep a short list on your phone

Keep a running list in your notes app and add things when they run out. Stick to it in the store. Unplanned buys add up much faster than people think.

10. Shop less often

Every trip to the store is a chance to grab extra snacks. One planned shop a week, plus a quick top-up for milk or fruit if needed, keeps spending steady.

11. Try grocery pickup if you tend to impulse-buy

Free curbside pickup (many stores offer it above a minimum order) lets you see your running total as you shop and skips the snack aisle completely. Watch out for delivery fees and tips, though, since they can wipe out the savings. Cash back can claw a little of it back: Nexus Rewards #ad lists cash back at over 3,500 stores in its Benefits Hub, so check whether your store is one of them.

12. Set a weekly number and track it

Pick a realistic weekly amount and keep your receipts for a month. You'll quickly see where the money goes, whether that's coffee pods, snacks or that "just one thing" trip on Wednesday.

Sample $40 weekly grocery list for one

Prices change by store and region, so treat these as rough examples based on discount-grocer prices. This list assumes you already have basics like oil, salt, pepper and a few spices.

Proteins

• 1 dozen eggs – about $3
• 1.5 lb chicken thighs (split and freeze in portions) – about $4.50
• 1 can black beans – about $1
• 1 bag dried lentils (1 lb) – about $1.50

Grains and bread

• Rolled oats (store brand, 18 oz) – about $2.50
• 2 lb bag of rice – about $2
• 1 loaf whole wheat bread (freeze half) – about $2
• 1 pack small flour tortillas – about $2

Produce

• 1 bag spinach – about $2.50
• 3 bananas – about $1
• 1 onion and 1 head of garlic – about $1.50
• 2 bell peppers – about $2
• 1 bag carrots (2 lb) – about $1.50

Frozen and canned

• 1 bag frozen mixed vegetables – about $1.50
• 1 bag frozen berries – about $3
• 1 can crushed tomatoes – about $1.50

Dairy

• 1 half-gallon milk – about $2
• 1 block shredded cheese (8 oz) – about $2.50
• 1 tub plain yogurt (32 oz) – about $3

Rough total: about $40

That's enough for a week of breakfasts (oats with berries and banana, or eggs on toast), lunches built from leftovers, and dinners like the ones below. Rice, oats and lentils will last into the next week too, so week two should cost less.

Single-serving meal-prep ideas

Cook these once and get two or three meals from each. Freeze anything you won't eat within 3 days.

• Chicken and veggie rice bowls: roast chicken thighs with peppers and carrots, serve over rice, and top with yogurt mixed with garlic. Makes 3 bowls.
• Lentil and tomato soup: onion, carrots, garlic, lentils and crushed tomatoes simmered for 30 minutes. Makes 4 portions, and it freezes well in single containers.
• Black bean quesadillas: mash beans with spices, add cheese and spinach, then toast in a dry pan. Make two and keep the filling for later in the week.
• Spinach and cheese egg muffins: whisk 6 eggs with spinach, peppers and cheese, then bake in a muffin tin. Grab-and-go breakfasts for 3 days.
• Freezer burritos: fill tortillas with rice, beans, cheese and leftover chicken, wrap each one in foil and freeze. Reheat for a quick lunch.
• Overnight oats: oats, milk and yogurt in a jar with berries. Make 3 jars on Sunday night.

Tip: single-portion containers cost very little and make leftovers feel like a meal instead of a chore. Label them with the date so nothing gets lost at the back of the freezer.

Mistakes that quietly cost solo shoppers money

• Buying family packs "because they're cheaper" without a plan to freeze or use them.
• Going shopping hungry, which leads to snacks and ready meals.
• Buying too much fresh produce at once, then watching it wilt.
• Relying on single-serve convenience foods, which cost far more per ounce.
• Skipping the freezer, which is the cheapest tool solo shoppers have for cutting waste.

If you ever cook for more people, or want more cheap meal ideas that scale up, see our guide on the cheapest way to feed a family of 4. Most of those meals halve easily for one.

Final take

Saving money on groceries for one person comes down to three things: plan a few meals that share ingredients, buy only the fresh food you'll finish, and let your freezer handle the rest. Start with the $40 list above, cook two of the meal-prep ideas this week, and track what you spend. Small habits like these add up quickly when you're the only one eating.
