If you’ve ever found yourself standing in the kitchen at 5 PM, wondering what to make with a fridge full of mismatched ingredients and no plan in sight — you’re not alone. Underplanning dinner is one of the fastest ways to turn a simple meal into a stressful scramble.

This post covers three common underplanning mistakes that make dinnertime harder than it needs to be. We’ll also walk through simple ways to fix each one so you can get dinner on the table faster (with less stress).

Mistake #1: Planning the Main Dish but Forgetting the Sides

Why it happens: You’re focused on the star of the meal and assume you’ll figure out the rest later.

Why it backfires: Come dinnertime, the main dish is ready, but the meal feels incomplete. You end up scrambling for a side, or worse, serving a half-finished meal.

What to do instead: When you plan dinner, treat it like a full plate. Ask yourself, “What else would make this meal feel finished?” Even a simple salad or frozen veggie counts.

Mistake #2: Not Checking What You Already Have on Hand

Why it happens: You’re in a rush or planning in your head, not from your pantry.

Why it backfires: You assume you have something, but you’re out. Or worse — you buy more of what you already had. This adds to food waste and makes dinner prep harder than it needs to be.

What to do instead: Before you plan, take a quick peek in your fridge, freezer, and pantry. Let what you already have guide what you plan to make.

Mistake #3: Skipping the Grocery List Altogether

Why it happens: You think you’ll remember. Or you’re just trying to get in and out of the store fast.

Why it backfires: Something always gets forgotten. And that one missing item can throw off your whole dinner plan.

What to do instead: Always jot down a quick list — even if it’s in the notes app on your phone. It saves time, money, and stress later.

Dinner doesn’t need to be a last-minute guessing game. A few small planning habits — like thinking beyond the main dish, checking your kitchen first, and bringing a grocery list — can save you loads of stress later.

Next time you’re tempted to wing it, remember: underplanning might feel easier in the moment, but it always makes dinner harder in the end.
