I Replaced All My Cooking Oils with Coconut Oil for 90 Days: Here's What Happened

When I first heard about people doing a coconut oil 90 day trial for their cooking needs, I was skeptical. Could one oil really handle everything from sautéing vegetables to baking cookies? As someone who had a kitchen cabinet full of different oils—olive oil for salads, vegetable oil for frying, butter for baking—the idea of simplifying to just coconut oil seemed both intriguing and potentially limiting.

This case study documents my personal experience of cooking only with coconut oil for three months straight. I'll share what worked, what didn't, and the surprising observations I made along the way. This isn't medical advice—it's simply one person's educational journey through a coconut oil cooking experiment.

The Challenge: Why I Decided to Try Cooking Only with Coconut Oil

My motivation came from three main factors: simplicity, curiosity about coconut oil's versatility, and wanting to better understand this ingredient that seemed to have such a devoted following. I'd read various discussions about coconut oil for cooking applications, but I wanted firsthand experience.

The rules I set for myself were straightforward:

• Replace ALL cooking fats with coconut oil (refined and unrefined varieties allowed)
• No olive oil, vegetable oil, butter, or any other cooking fats
• Track cooking performance, taste outcomes, and any notable observations
• Document both successes and failures honestly
• Continue my normal eating patterns otherwise

Before starting, I stocked up on both refined coconut oil (for high-heat cooking and neutral flavor needs) and unrefined coconut oil (for medium-heat cooking and when I wanted that subtle coconut flavor).

Week 1-2: The Learning Curve

The first two weeks were definitely an adjustment period. Switching to coconut oil cooking required relearning some basic techniques I'd taken for granted.

Temperature Management

Coconut oil's smoke point became immediately relevant. Refined coconut oil handles higher temperatures well (around 400°F), but I learned to be more mindful of heat levels. My usual high-heat searing techniques needed modification.

Texture Considerations

At room temperature, coconut oil is solid below 76°F. This meant planning ahead for recipes that required liquid oil, or gently warming the oil first. I found myself keeping a small jar near the stove for easy access.

Early Cooking Observations

• Sautéing vegetables: Worked beautifully with both refined and unrefined versions
• Scrambled eggs: Excellent results—eggs didn't stick and had a pleasant richness
• Baking attempt #1 (cookies): Mixed results—texture was different but not unpleasant
• Salad dressing: Required warming the oil first, which felt awkward initially

Week 3-6: Finding My Rhythm

By the third week, I'd developed new habits and workarounds that made the coconut oil cooking experiment feel more natural.

Cooking Technique Adaptations

I learned to embrace medium-heat cooking more than I had before. This actually improved some of my cooking—vegetables retained more of their texture and color when I wasn't blasting them with high heat.

For baking, I discovered that melting the coconut oil and letting it cool slightly before mixing created better incorporation than trying to cream solid coconut oil with sugar (though both methods worked).

Flavor Profile Discoveries

Unrefined coconut oil added a subtle tropical note to many dishes that I began to appreciate. It was particularly good with:

• Stir-fried Asian dishes
• Roasted vegetables
• Pancakes and quick breads
• Curry-based dishes (naturally complementary)

Refined coconut oil proved virtually flavorless, making it suitable for dishes where I didn't want any coconut taste.

Unexpected Challenges

Making salad dressings remained awkward throughout the experiment. While coconut oil-based dressings worked, they required advance planning to warm the oil for mixing, and they'd solidify if the salad was cold.

High-heat cooking techniques like getting a perfect sear on steak required more patience and technique adjustment.

Week 7-12: Mastery and Observations

The final six weeks felt like I'd found my groove with coconut oil cooking. I'd developed intuitive knowledge about which type to use when, and my cooking techniques had adapted.

Cooking Performance Assessment

Taste and Texture Observations

Most dishes tasted either identical to my previous cooking methods or had a subtle improvement in richness. The coconut flavor from unrefined oil was generally mild and pleasant, even in dishes where I hadn't expected it to work well.

Baked goods had a slightly different texture—often a bit more tender and moist. Some family members actually preferred cookies and muffins made with coconut oil.

Practical Considerations I Discovered

Storage and Handling

I learned to keep coconut oil in different locations based on my cooking needs:

• A small jar near the stove for quick access
• Main supply in the pantry
• A portion in the refrigerator during summer months when room temperature was consistently above 76°F

Cost Analysis

Initially, coconut oil seemed more expensive per ounce than my previous mix of oils. However, using only one type of oil eliminated waste from bottles of specialty oils going rancid, and I found I actually used less oil overall due to coconut oil's efficiency in cooking.

Seasonal Considerations

Summer cooking with coconut oil required slight adjustments due to the warmer ambient temperature keeping the oil liquid more often. Winter meant planning ahead for solid oil more frequently.

What I Learned About Coconut Oil's Versatility

This experiment gave me deep appreciation for coconut oil's range of applications. The coconut oil for cooking possibilities seemed almost endless once I understood how to work with its unique properties.

The key insight was that coconut oil isn't necessarily better or worse than other cooking oils—it's different, and those differences can be advantages once you understand them.

Standout Success Categories

• Breakfast foods: Pancakes, eggs, and hash browns all benefited from coconut oil's properties
• Roasted vegetables: Consistently excellent results with great caramelization
• Asian-inspired dishes: The subtle coconut flavor complemented these cuisines naturally
• Baked sweet goods: Muffins, quick breads, and cookies had improved texture and taste

Challenges That Remained

Honesty requires acknowledging that some applications never felt quite as convenient as my previous methods:

• Cold salad dressings required workarounds
• Very high-heat cooking techniques needed adjustment
• Some Mediterranean dishes missed the distinct olive oil flavor
• Certain delicate pastries worked better with butter's specific properties

Beyond the Kitchen: Additional Observations

While this experiment focused on cooking performance, I noticed some other changes during the 90 days. It's important to note that these observations could be influenced by many factors, and individual experiences may vary significantly.

I observed what seemed like more stable energy levels throughout the day, though this could have been related to other dietary or lifestyle factors during the same period. Some research suggests that coconut oil's medium-chain triglycerides may be metabolized differently than other fats, but more research is needed to understand these mechanisms fully.

For anyone curious about potential coconut oil health benefits or concerns about coconut oil cholesterol effects, I'd recommend consulting with a qualified healthcare provider who can provide personalized guidance based on your individual health profile.

Key Takeaways from My 90-Day Coconut Oil Experiment

What Worked Exceptionally Well

• Kitchen simplification—one oil for most needs
• Improved vegetable roasting results
• Enhanced texture in many baked goods
• Stable, long-lasting cooking performance
• Pleasant, subtle flavor enhancement in many dishes

What Required Adjustment

• Planning ahead for solid vs. liquid oil states
• Modifying high-heat cooking techniques
• Finding workarounds for cold applications
• Accepting different flavor profiles in some traditional dishes

Would I Continue?

After completing the coconut oil 90 day trial, I found myself continuing to use coconut oil as my primary cooking oil, though I did reintroduce olive oil for specific applications where its flavor was particularly important.

The experiment taught me that coconut oil could handle far more cooking applications than I'd initially expected, and many of the results were equal to or better than my previous methods.

Final Thoughts

This coconut oil cooking experiment was ultimately about understanding ingredients better and challenging assumptions about kitchen "essentials." While individual experiences will vary, and coconut oil isn't necessarily superior to all other cooking oils in every application, it proved to be remarkably versatile.

For anyone considering a similar experiment, I'd suggest starting with a shorter trial period—perhaps two weeks—to see how coconut oil fits your cooking style before committing to a longer timeframe.

The most valuable outcome wasn't proving that coconut oil is "the best" cooking oil, but rather discovering that thoughtful ingredient choices can simplify your kitchen while potentially enhancing your cooking results.
