What Foods Should I Never Make From Scratch?

Let me tell you a secret that might sound like heresy in the world of cooking blogs: you do not have to make everything from scratch. There, I said it. I remember being a new cook, believing that to be a ‘real’ one, my pantry had to be free of boxes and my refrigerator full of only the most basic, elemental ingredients. I once spent an entire Saturday trying to make puff pastry, ending up with a buttery, leaky mess and a very bruised ego.

The truth is, the best cooks aren’t the ones who do everything the hard way. The best cooks are the ones who make delicious food, and they know the most valuable ingredient in any kitchen is your own time and energy. It’s all about a smart return on your investment. Some things are absolutely transformed when made at home. Others? The difference is tiny, and the effort is enormous. Let’s break down where to spend your energy and where to happily grab that grocery store shortcut.

My ‘Better Bought’ List Where to Save Your Sanity

Think of this as your official permission slip to not do it all. These are items where the store-bought version is often just as good (and sometimes, for specific purposes, even better) than a homemade attempt, especially when you’re starting out.

• Puff Pastry & Phyllo Dough: This is my number one. The process of making these laminated doughs involves creating hundreds of paper-thin layers of butter and dough through a meticulous process of chilling, rolling, and folding. It’s technically demanding and requires a cold kitchen. High-quality frozen brands like Pepperidge Farm or Dufour are used by professional bakers for a reason. They are consistent, reliable, and produce a beautiful result. Don’t waste your Saturday on this one. (Your future self will thank you.)

• Ketchup & Most Condiments: Can you make your own ketchup? Absolutely. It involves simmering tomatoes, vinegar, sugar, and spices for hours to get the right consistency. But will it taste like the iconic Heinz you grew up with? Probably not. For everyday use, bottled condiments are perfectly fine. Focus your energy on the burger patty, not the ketchup for the fries.

• Certain ‘Junk Food’ Duplicates: This one might be controversial. I love a good homemade brownie. But if you are specifically craving a fudgy, slightly chewy, box-mix-style brownie, trying to replicate that texture from scratch can be tricky. Store-bought mixes and snacks often use stabilizers and emulsifiers that are hard to mimic at home. Sometimes a homemade brownie ends up too cake-like or a frosting slides right off because it lacks those commercial-grade stabilizers. If you want a specific nostalgic treat, sometimes the box is the best way to get it.

• Worcestershire Sauce: The ingredient list on a bottle of Lea & Perrins is long and complex, involving things like anchovies, tamarind extract, and molasses that are fermented and aged. Replicating that unique, umami-rich flavor at home is a massive undertaking for a very small reward. Just buy the bottle.

Where Your Effort Truly Shines

Now, for the fun part! These are the items where making them from scratch provides a massive upgrade in flavor and quality. The return on your time investment here is huge, and they are often simpler than you think.

• Salad Dressing: This is the easiest kitchen win. A basic vinaigrette is just three parts oil to one part vinegar, plus a pinch of salt and pepper. Put it all in a jam jar with a teaspoon of Dijon mustard (to help it emulsify), shake it for 10 seconds, and you have a dressing that tastes a million times fresher than anything from a bottle. No weird gums or sugars, just pure, bright flavor.

• Chicken or Vegetable Stock: Simmering leftover chicken bones or vegetable scraps (onion peels, carrot ends, celery tops) with water creates a liquid gold that will transform your soups, sauces, and grains. It makes your whole house smell incredible and gives your cooking a depth of flavor that a bouillon cube just can’t match.

• Whipped Cream: Forget the can. Pour cold heavy whipping cream into a bowl (chilling the bowl and beaters helps!) and beat it with a hand mixer or in a stand mixer like a KitchenAid. Add a little powdered sugar and a splash of vanilla once it starts to thicken. In about 3-5 minutes, you’ll have luscious, airy, real whipped cream. The difference in taste and texture is astonishing.

• Simple Sauces: A basic tomato sauce for pasta is one of the most rewarding things to make. Sauté some garlic in olive oil, add a 28-ounce can of crushed tomatoes (San Marzano are great if you can find them), a pinch of salt, and some fresh basil. Let it simmer for 20 minutes. That’s it. It’s a universe away from most jarred sauces.

The Golden Rule It’s Your Kitchen Your Rules

Here’s the real takeaway: there is no universal right or wrong. The goal of cooking is to add joy to your life, not stress. If you absolutely love the process of making pasta by hand, do it! If the thought of it makes you want to order takeout, then buy the good quality dried stuff. Being a smart cook is about knowing your priorities. On a busy Tuesday, that might mean using a jar of sauce to get a wholesome dinner on the table. On a lazy Sunday, that might mean simmering that sauce from scratch. Both are valid, and both make you a great home cook.

Try This Tonight: Grab a nearly empty jam jar. Add three tablespoons of olive oil, one tablespoon of red wine vinegar, a small squeeze of Dijon mustard, and a pinch of salt and pepper. Screw the lid on tight and shake it like crazy for 15 seconds. You’ve just made a delicious, fresh vinaigrette for your salad. See? You’re already making magic from scratch, one easy step at a time.
