Short answer: The cheapest way to shop plant-based is to build the cart around dried or canned beans, lentils, oats, rice, frozen vegetables and whatever fresh produce is in season. Fancy "superfoods" and specialty products are optional. Below are a budget staple list, a seasonal produce guide and tips for storing what you buy.
The budget staples list
These are the foods that do the most work for the least money. Prices vary by region, so check unit prices on the shelf tag.
| Category | Best-value picks | Why |
|---|---|---|
| Legumes | Dried lentils, dried or canned chickpeas, black beans, split peas | Protein and fiber at low cost per serving |
| Grains | Rolled oats, brown rice, whole-wheat pasta, store-brand quinoa | Cheap, filling, keep for months |
| Frozen | Spinach, broccoli, mixed vegetables, berries | Picked ripe, no waste, often cheaper than fresh |
| Long-keeping produce | Cabbage, carrots, onions, sweet potatoes, apples, bananas | Last 1 to 4 weeks |
| Canned | Diced tomatoes, coconut milk, low-sodium beans | Fast dinners from the pantry |
| Protein extras | Firm tofu, peanut butter, sunflower seeds | Cheaper than most nuts |
USDA's Thrifty Food Plan, the government's own low-cost food budget, leans on many of these same foods [1].
Shopping by season
Produce in season is usually cheaper and tastes better. A rough U.S. guide, based on the USDA SNAP-Ed seasonal produce guide [2]:
- Spring: asparagus, peas, spinach, strawberries, radishes
- Summer: tomatoes, zucchini, corn, peppers, peaches, berries, melons
- Fall: apples, pears, squash, sweet potatoes, Brussels sprouts, cauliflower
- Winter: citrus, kale, cabbage, carrots, leeks
Store-by-store tips
- Discount grocers (Aldi, Lidl): strong on produce, oats, canned beans and frozen vegetables. Check the weekly produce specials.
- Trader Joe's: good for pre-cooked lentils, frozen grains and nuts in smaller bags; less useful for bulk staples.
- Warehouse clubs (Costco, Sam's Club, BJ's): best for bulk frozen fruit, quinoa, nuts and olive oil if you have the freezer and pantry space.
- Ethnic and international markets: often the cheapest place for dried beans, lentils, rice, spices and greens.
We don't receive anything from these stores. Prices and stock change; this is a starting point, not a ranking.
Washing and storing produce
- Rinse produce under running water just before eating, not before storing. Soap and produce washes aren't needed [3].
- Keep onions, potatoes and sweet potatoes in a cool, dark place, apart from each other.
- Store leafy greens wrapped in a dry towel in a container in the fridge.
- Freeze ripe bananas and berries for smoothies before they spoil.
- Check the FoodKeeper app for how long cooked beans and grains last [4].
A one-week starter cart
Two greens, two other vegetables, one bag of frozen vegetables, three fruits, one dried or canned legume, one canned bean, one grain, oats, one nut or seed, and a lemon. That covers the base of our 7-day meal plan. Use the Electric Food List to swap items you don't like.
