How to Meal Prep on a Budget
Meal prepping can slash your weekly food spend significantly — the average American spends $13 per meal eating out versus $4 cooking at home. But budget meal prep requires planning. Here's a practical system that works.
The Best Budget Proteins
Protein is usually the most expensive part of any meal. These are the best value options by cost per gram of protein:
| Protein | Avg cost per lb | Cost per 25g protein |
|---|---|---|
| Dried lentils | $1.50 | ~$0.30 |
| Canned chickpeas | $1.00 | ~$0.35 |
| Eggs | $4.00/dozen | ~$0.50 |
| Chicken thighs | $2.50 | ~$0.65 |
| Ground turkey | $3.50 | ~$0.75 |
| Canned tuna | $1.50/can | ~$0.60 |
| Chicken breast | $4.00 | ~$0.90 |
The $50/Week Meal Prep System
A practical budget for one person eating home-cooked meals 5 days a week. The structure: one batch protein, two grain/carb options, three vegetable sides, and flexible snacks.
Start by planning 5 dinners and 5 lunches. Lunches are often dinner leftovers — this halves your cooking time. Calculate your expected cost per serving with our Cost Per Serving Calculator before you shop.
Best Budget Staples to Always Have
These pantry staples are cheap, last long, and form the base of dozens of meals: dried rice, dried lentils, canned tomatoes, canned beans, oats, eggs, frozen vegetables, garlic, onions, and olive oil. Building meals around what you already have reduces waste dramatically.
Dried beans and lentils are far cheaper than canned — typically 50–60% less per serving. The trade-off is soaking time (dried beans need 8 hours) but lentils need no soaking at all and cook in 20–25 minutes.
How to Actually Save at the Grocery Store
Buy proteins in bulk and freeze portions. Chicken thighs are almost always cheaper per pound than breasts and are harder to overcook. Shop seasonally for vegetables — in-season produce can be 50–70% cheaper than out-of-season. Store brand staples like rice, beans, and pasta are typically identical to name brands.
Check the unit price (price per ounce or per pound) on the shelf label, not the package price. The larger size is usually but not always cheaper — verify before assuming.
Batch Cooking vs. Full Meal Prep
Full meal prep means assembling complete meals for the week. Batch cooking means preparing components separately — a batch of rice, a batch of roasted vegetables, a batch of protein — and mixing them throughout the week. Batch cooking is more flexible and less likely to lead to food fatigue. Both work; most budget meal preppers use a mix of both.

Frequently Asked Questions
How much should meal prep cost per week for one person?
A realistic budget meal prep for one person eating at home for all lunches and dinners is $40–60 per week, or $2–4 per meal. This assumes cooking from scratch with pantry staples and a focus on affordable proteins like eggs, legumes, and chicken thighs. Breakfasts bring the total higher if included.
What are the cheapest meals to batch cook?
Lentil soup, rice and beans, vegetable stir-fry with eggs, oatmeal, pasta with homemade tomato sauce, and chicken thigh stews are consistently among the cheapest options at $1–2 per serving. These meals are also filling and high in protein, making them sustainable for the week.
How long does meal prepped food last in the fridge?
Most cooked proteins and grains last 4–5 days refrigerated. Soups and stews last 4–5 days. Roasted vegetables last 3–4 days. Salads (undressed) last 4–5 days. If you're prepping for a full week, freeze the last 2 days of food and thaw Thursday night.
Is meal prepping worth it financially?
Yes, for most people — significantly so. Even a modest shift from eating out twice a week to home-cooked meals saves the average person $80–150 per month. The time investment is typically 2–3 hours on the weekend for a full week of meals.
