Homemade Grill Sauces vs Bought: The Cost Test

Homemade grill sauces are cheaper than bought ones almost every time — typically 50 to 70 percent less per portion. A bottled BBQ sauce, aioli or herb dip costs CHF 2.60 to 3.50; the same amount made from pantry staples costs roughly CHF 0.90 to 1.30. You also control the sugar, salt and additives.

Over a summer of weekend grilling — a dozen barbecues, three sauces each — swapping bottles for homemade saves a household around CHF 60 to 80. That is money the average Swiss household, which already spends about CHF 636 a month on food and non-alcoholic drinks (Federal Statistical Office), barely notices leaving through the sauce shelf.

What a bottled sauce actually costs you

Pick up a branded barbecue sauce and you are paying for four things: a little tomato and vinegar, a lot of water and sugar, the bottle, and the brand on the label. The edible part is cents. Swiss shelf prices make the gap sharper still — groceries here run about 61% above the EU average — with a mid-range BBQ bottle sitting at CHF 3.20 to 3.90 and a small tube of aioli at CHF 2.80 to 3.50.

Per portion that looks harmless: a bottle holds ten to twelve servings, so each spoonful is 30 rappen or so. The catch is that a grill table rarely uses one sauce. A barbecue for four with BBQ sauce, a garlic aioli and a herb dip means three open bottles, and most of each is still sitting in the fridge door two months later, half of it eventually binned. Buying only the sauces you actually use, in the amount you actually need, is where homemade wins.

Three grill sauces from pantry basics

These three cover almost any grill: one sweet-smoky, one rich and garlicky, one fresh and herby. None needs special kit, and all of them lean on staples you likely already own — the same argument for keeping a well-stocked spice rack on a budget.

Smoky BBQ sauce. Simmer 250 g passata or tomato purée with two tablespoons brown sugar, one tablespoon vinegar, a teaspoon of mustard, a teaspoon of paprika and a pinch of salt for ten minutes. That is a 400 g batch for about CHF 1.30 using own-brand ingredients from Aldi, Lidl or Denner, and it keeps for two to three weeks.

Garlic aioli. Whisk one egg yolk with a little mustard, then trickle in 150 ml oil drop by drop, whisking hard, until it thickens into mayonnaise. Beat in a crushed garlic clove, a squeeze of lemon and salt. No blender, no food processor: a bowl and a whisk are enough, provided the ingredients are at room temperature and you add the oil slowly. Cost, under CHF 1.

Herb yogurt dip. Stir a handful of chopped chives and parsley plus a grated garlic clove into 200 g plain yogurt or quark, with lemon, salt and pepper. Two minutes, about CHF 1, and it doubles as a salad dressing.

The cost test, sauce by sauce

Here is the side-by-side for a typical Swiss grill, comparing a branded bottle against the same volume made at home from own-brand staples.

Six francs saved per barbecue is not a revolution on its own. Across a summer it is, and it stacks on top of what you already save by buying the meat itself well — see our Swiss grill meat price comparison for where the bigger wins hide.

How long do homemade grill sauces keep?

Shelf life is the one place a bottle has a real edge, so it pays to match the batch to the base:

• Tomato-and-vinegar BBQ sauce: two to three weeks in a clean, sealed jar in the fridge. The acidity does the preserving.
• Egg-based aioli: two to three days, no more — raw yolk is perishable. Make it the morning of the grill.
• Yogurt or quark herb dips: three to four days, and best stirred fresh.
• Oil-and-herb sauces (chimichurri): up to a week; the oil seals the herbs from the air.

Two habits keep sauces safe in summer heat: serve with a clean spoon rather than dipping used cutlery, and keep the jar in the fridge until the food hits the grill, not out on the table all afternoon. Care around raw egg matters most on hot days.

Make a summer's worth in twenty minutes

The trick is to treat sauce-making as one small session, not a nightly chore:

1. Check the flyers first. Note which store has oil, eggs, tomato products or yogurt on Aktion this week — those are your sauce bases.
2. Buy own-brand. For sauce ingredients, the discounter or own-label version performs identically once mixed and seasoned. Nobody tastes the brand of your passata.
3. Make the keepers ahead. Simmer the BBQ sauce and mix any oil-based dressing at the start of the week; both hold for days.
4. Make the perishables fresh. Whisk the aioli and stir the yogurt dip on grill day itself.
5. Label and date the jars. A strip of tape with the date stops the guessing game — and the waste.

Let the app watch the ingredient prices

Homemade only stays cheap if the raw ingredients are bought well, and oil, eggs and dairy all move on and off promotion constantly across the chains. This is the legwork Eini's algorithm handles: it tracks current prices on your sauce staples across Coop, Migros, Lidl, Aldi, Denner and Aligro, then folds them into the meal plan and grocery list so a batch of sauce is built from whatever is cheapest that week. It is the same logic behind our look at homemade versus store-bought snacks — small swaps, repeated, that add up.
