The 5 Meal Prep Mistakes That Are Actually Making You LESS Prepared for Emergencies

Last updated: 27th October 2025 | 8 minute read

Let me guess—your Instagram feed is full of those perfect meal prep photos. Thirty matching glass containers. Colour-coordinated vegetables. Portions so precise they could be in a museum.

Here’s the uncomfortable truth: If a real emergency hit tomorrow, most of these “preppers” would be eating cold quinoa salad by candlelight while their freezer full of perfectly portioned meals defrosts.

I learned this the hard way during the 2020 lockdowns. While my neighbours with their Pinterest-perfect meal preps scrambled when shops emptied, those of us with actual preparedness systems adapted seamlessly. The difference? We understood that meal prep isn’t just about next week’s lunches—it’s training for genuine food security.

Let me tell you the 5 meal prep mistakes that are actually making you LESS prepared for emergencies, and how to fix them.

Mistake #1: Depending Entirely on Refrigeration

The Instagram Version: 30 fresh meals in gleaming containers, taking up the entire fridge.

The Problem: What happens when we get another Storm Arwen that leaves thousands without power for a week? Or when panic buyers empty Tesco and there’s no fresh produce for a fortnight?

During Storm Eunice, families in my area lost power for four days. Those with freezers full of expensive meal prep watched £200+ of food spoil. Meanwhile, those who understood shelf-stable prep barely noticed the disruption.

Last winter’s cold snap saw rolling power cuts across the UK. My neighbour with her “perfect” meal prep system lost everything in her freezer—three weeks of prepped meals, gone.

The Fix:

Mistake #2: Single-Point-of-Failure Systems

The Instagram Version: Every meal needs the microwave, or the slow cooker, or that specific brand of protein powder from Holland & Barrett.

The Problem: Creating dependencies on single tools or ingredients makes your entire system fragile.

I watched a neighbour’s meal prep system collapse because she built everything around her electric pressure cooker. No power? No meals. Another friend couldn’t function when her special organic delivery box stopped during lockdown—she’d never learned to shop and prep without it.

Remember the KFC chicken “crisis” of 2018? Now imagine that’s your protein powder, specialist flour, or whatever single ingredient your system depends on.

The Fix:

  • Learn multiple cooking methods for the same ingredients
  • Practice “no-power” meal assembly monthly
  • Stock versatile ingredients that work raw, cooked, or preserved
  • Keep a camping stove and know how to use it, the Campingaz Camp Bistro is smaller that the above.
  • Have British alternatives for specialty ingredients

Mistake #3: The “All or Nothing” Perfection Trap

The Instagram Version: If you can’t prep 21 meals with macros calculated to the gram, why bother?

The Problem: This mindset crumbles under real pressure. When actual emergencies hit, perfection becomes the enemy of feeding your family.

During the first COVID lockdown, I watched “perfect preppers” completely abandon their systems when Sainsbury’s ran out of chicken breast and sweet potatoes. They had no flexibility, no substitution skills, no ability to adapt. Meanwhile, those of us with “good enough” systems just switched to chicken thighs and regular potatoes and carried on.

The lorry driver shortage of 2021 proved this again—those who could only follow exact recipes panicked, while flexible preppers simply adapted.

The Fix:

  • Master component prep, not just complete meals
  • Learn ingredient substitution rules (crucial with UK supply chain issues)
  • Practice “use what you have” weeks
  • Build flexibility into your system from day one
  • Know how to swap between British seasonal produce

Mistake #4: Ignoring Food Fatigue

The Instagram Version: The same grilled chicken and broccoli, 14 meals a week, forever.

The Problem: In a real crisis lasting weeks or months, food boredom becomes food refusal—especially with children. Mental health during emergencies partly depends on food comfort and variety.

A friend in Somerset who survived three weeks of flooding isolation told me her kids stopped eating after day four of the same emergency meals. Not because they weren’t hungry, but because the psychological impact of repetitive crisis food compounded their stress.

During the Beast from the East, families snowed in for a week discovered that morale dropped dramatically when meals became monotonous.

The Fix:

  • Prep components that combine into different meals
  • Stock British comfort foods alongside healthy options
  • Master spice cupboard variety [Amazon affiliate: ProCook Spice Rack Set]
  • Learn three ways to prepare each protein
  • Include comfort foods in your emergency prep (yes, even biscuits)
  • Rotate cuisines weekly (curry Monday, roast Tuesday, pasta Wednesday)

Mistake #5: Prepping in Isolation

The Instagram Version: Solo Sunday prep sessions, headphones on, world out.

The Problem: You’re creating a system only you understand. What happens if you’re ill, injured, or isolating when crisis hits?

During my COVID isolation, I was too sick to explain my “perfect” system to my partner. If I hadn’t previously taught him the basics, the family would’ve been living on beans on toast for two weeks (if bread was available).

The Fix:

  • Involve family members in prep sessions
  • Write your system down clearly Magnetic Weekly Meal Planner
  • Teach at least one backup person your full process
  • Create an “emergency meal manual” for your household
  • Build community connections—that WhatsApp group with neighbours matters

The British Lockdown Reality Check

Remember March 2020? Empty shelves at Asda. Two-hour queues at Aldi. No delivery slots for three weeks. The preppers who thrived weren’t the ones with colour-coordinated containers. They were the ones who:

  • Had diverse food storage (fresh, frozen, tinned, dried)
  • Could cook on camping stoves when worried about smart meter credit
  • Knew how to make flour stretch when shops limited purchases
  • Had family members who understood the system
  • Connected with neighbours for resource sharing

My mate Sophie had the most Instagram-worthy meal prep setup you’ve ever seen. Two weeks into lockdown, she was panic-buying pasta at the corner shop with everyone else because her system couldn’t adapt to missing ingredients and empty Waitrose shelves.

Meanwhile, boring old me with my mixed-method approach? I was teaching neighbours how to make soda bread from stockpiled flour and sharing preserved veg from the previous summer’s allotment harvest.

Building Anti-Fragile British Meal Prep

True preparedness means your system gets stronger under pressure, not weaker. Here’s your foundation:

Week 1-2: Master fresh prep while learning one preservation method Week 3-4: Practice “power cut” meal assembly (remember, British homes often have gas hobs even when electric’s out) Month 2: Build two-week shelf-stable rotation using British tinned goods Month 3: Teach someone else your system completely

The Real Test

Ask yourself honestly: If shops closed tomorrow for two weeks, or we had Storm Arwen-style power cuts, or you had to isolate suddenly—would your current meal prep system help or collapse?

If the answer makes you uncomfortable, it’s time to evolve from Instagram meal prep to genuine food preparedness.

Your action step: This Sunday, prep one meal using ONLY shelf-stable ingredients and no electricity (yes, that includes no electric hob). That single exercise will teach you more about real preparedness than a thousand perfect containers ever could.
