Tomatoes slide, potatoes roll, onions do both while making you cry - the batch-cooking staples are, almost without exception, annoying to slice by hand. They are also the vegetables that benefit most from uniformity: even tomato slices roast evenly, even potato slices cook through at the same rate. An onion holder slicer handles the whole awkward family: the stainless guide holds onions steady, and your onion holder slicer works on tomatoes and potatoes too, keeping slices even across all of them. For beginners prepping sunday batch-cooking sessions, that versatility matters - one tool steadies nearly everything you slice in volume. The 15 ideas below lean on these staples because they are cheap, filling, and endlessly flexible. This tool makes them fast and safe to prepare.
1. Hard-Boil a Dozen Eggs
Twelve eggs, boiling water, eleven minutes, ice bath — and you have the most versatile protein in the prep game. Snacks, salads, breakfasts, grain bowls: hard-boiled eggs improve all of them. They keep a full week refrigerated in their shells.Beginners: this is more forgiving than it looks — the steps are simple and mistakes still taste fine.
2. Portion Smoothie Bags
Freezer bags of smoothie ingredients — fruit, spinach, protein powder portions — ready to dump and blend. Mornings become a sixty-second operation instead of a produce-chopping session. A month of bags takes twenty minutes to assemble. Meal prep means serious onion volume; an onion holder slicer holds each one steady while you work through the bag. No more wedge lottery - it keeps the spacing even across the whole vegetable.
Storage discipline makes or breaks portion smoothie bags: cool completely, portion honestly, label the freezer bags. Even slices earn their keep here too - uniform pieces freeze and reheat more evenly than a mix of thick and thin. The consistency behind those slices comes from the onion holder slicer: same spacing, same steady hold, every time. Good storage starts with even knife work.
3. Make a Big-Batch Soup
A stockpot of soup on Sunday is lunches and dinners for days. Lentil, minestrone, chicken noodle, butternut squash — soups are forgiving, freezable, and reheat perfectly. Make more than fits the week and freeze the surplus for a future rescue meal.
4. Label and Freeze Portions
The unglamorous job that makes everything else work: portion surplus into freezer bags or containers, label with contents and date, freeze flat for easy stacking. Future-you will not remember what's in the mystery bag — label now, thank yourself later. This ten-minute habit builds a freezer that actually gets used.
5. Prep Breakfast Components
Breakfast deserves its own prep slot: portion oats, bake egg cups, mix pancake batter (dry ingredients), chop fruit. Fifteen focused minutes eliminates five mornings of decisions. The components combine into different breakfasts, so nobody gets bored. Before a big session, set out an onion holder slicer - press the prongs in, slice with your own knife, and watch the pile grow. It works on tomatoes and potatoes too, steadying the whole slicing lineup.
6. Portion Nuts and Trail Mix
Nuts are the perfect prep snack — protein, healthy fats, zero preparation — but the bag is a portion-control disaster. Divide into small bags or containers: a week's worth of sensible portions in ten minutes. Add dried fruit and dark chocolate chips for trail mix.If you're new to prepping, start here; it's the lowest-stakes way to build the habit.
7. Set Up a Use-First Bin
Designate one fridge bin for foods that need eating soon — the half onion, the wilting herbs, the yogurt nearing its date. When it's time to cook, shop the bin first. This simple system cuts food waste dramatically with zero extra effort. Review it midweek and plan around what you find.
8. Roast a Whole Chicken
One roasted chicken is secretly three meals: sliced breast for bowls, shredded thigh meat for tacos, and a carcass for stock. It's the most economical protein in the prep world and the most flavorful. Roast Sunday, portion immediately, and the week is set. When the slicing list is long, an onion holder slicer keeps the rhythm going - confident cuts, even slices, guarded fingers. With the onion holder slicer holding it steady, the onion stops rolling and the slicing speeds up.
9. Build Salad Jars
Dressing on the bottom, hearty vegetables in the middle, greens on top — the layered jar keeps every component pristine until you're ready to shake and eat. Five jars, thirty minutes, and lunch is handled. They hold four to five days refrigerated.New cooks love this one because there's no precise technique to master, just straightforward steps.
10. Cook a Big Pot of Grains
Grains are the backbone of a prep week: rice, quinoa, farro, or barley cooked in bulk on Sunday become the base for countless meals. Cook more than you think you need — grains are cheap and endlessly versatile. Cool quickly, portion, and refrigerate; most keep five days. An onion holder slicer works on tomatoes and potatoes too, so the whole awkward family of round vegetables gets the same steady treatment. Press the prongs in and it guards your fingers while you slice confidently.
11. Make a Sauce Trio
Sauce is what turns the same ingredients into different meals. Blend a tahini-lemon dressing, a peanut sauce, and a chimichurri or salsa verde — three jars, fifteen minutes, and every bowl all week tastes different. Sauces keep five to seven days refrigerated.
If you are new to prepping, make a sauce trio is an ideal first project: simple steps, familiar ingredients, and food you will actually eat. Beginners should learn the safety rule early: steady the food, guard the fingers. This tool teaches both at once - the prongs hold the onion while your hand stays behind the stainless guard. It is the rare safety upgrade that also makes you faster.
12. Marinate for the Week
Proteins marinate while you do everything else. Bag chicken in yogurt-herb marinade, tofu in soy-ginger, pork in citrus-chili — refrigerate, and cook fresh through the week or freeze for later. Marinating is passive flavor that costs you two minutes.
The beauty of marinate for the week is how it scales - halve it for one, double it for the household, and the method never changes. More portions mean more slicing, which means the holder earns its keep even faster at scale. Your onion holder slicer keeps the rhythm steady whether it is two onions or ten. Scale the food; keep the fingers.
13. Assemble Overnight Components
Overnight oats, chia pudding, marinated tofu — the foods that improve with a night in the fridge should be assembled Sunday evening, not morning-of. Ten minutes of jar-filling before bed, and breakfast or lunch components are waiting. It's the lowest-effort prep job with the highest return.
14. Prep Proteins Two Ways
Two proteins, two seasonings, endless combinations. Roast chicken breasts with lemon-herb and bake salmon with soy-ginger, or brown ground turkey two ways — the variety prevents the dreaded protein fatigue. Slice or shred after cooking for grab-and-go portions. Uneven cuts cook unevenly; an onion holder slicer keeps slices uniform so the whole tray finishes at the same time. Confident cuts are fast cuts, and the onion holder slicer makes every cut confident.
15. Wash and Chop Produce
The single highest-leverage prep job: wash the greens, chop the vegetables, slice the fruit. Prepped produce gets eaten; whole produce wilts in the drawer. It takes thirty minutes and transforms your fridge from a storage unit into a salad bar. Store greens with a paper towel to absorb moisture. Smart preppers steady first: an onion holder slicer removes the sketchiest part of the board work in one motion. The stainless guide of it holds firm while your own knife does the work.
Gear That Pulls Its Weight

Frequently Asked Questions
How long does shipping take?
Estimated delivery times are 5–12 business days within Canada, 7–15 business days to the US, and 10–25 business days for international orders. These are estimates rather than guarantees — carriers and customs can add time, especially around holidays. You'll receive tracking information once your order ships so you can follow its progress.
What is the return policy?
Orders come with a 30-day return window. If something arrives damaged, defective, or simply isn't right for your kitchen, contact support within 30 days of delivery to arrange a return or replacement. Items should be unused and in their original packaging where possible.
Will my slices actually come out even?
More even than freehand, consistently. The guide sets your spacing and holds the vegetable still, which are the two things that make hand slicing uneven. Your cuts still depend on your knife work, but the onion holder slicer removes the wobble and the guesswork. Even slices cook evenly - and that is the payoff that matters for batch cooking.
Should I prep full meals or individual components?
Components, almost always. Full meals lock you into eating the same thing repeatedly; components let you assemble different meals from the same prep session. Cook your grains, proteins, and vegetables separately, prep one or two sauces, and mix freely through the week. The exception is freezable one-pot meals like soups and chilis, which are genuinely better prepped as finished dishes.
