When I think about building a defensive ASX portfolio, I'm looking for businesses with essential products, resilient earnings, and balance sheets strong enough to ride out economic cycles.
If I had to start that portfolio today, three names that would be near the top of my list are in this article.

CSL Ltd (ASX: CSL)
CSL has been a frustrating investment for many shareholders over the past couple of years. The biotech's share price has de-rated significantly from its highs, and there have been operational headwinds across parts of the business.
Influenza vaccine weakness in the US, softer demand for albumin in China, and slower-than-expected margin recovery in CSL Behring have weighed on sentiment. The disappointment around its CSL112 trial outcome also removed what many had hoped would be a meaningful growth driver.
There's no point pretending that period didn't happen. It did.
But from my perspective, that's precisely why the risk-reward now looks more favourable than it did when the stock was trading near its peak valuation.
CSL remains a global plasma leader with scale advantages that are difficult to replicate. Plasma collection networks, manufacturing expertise, and deep relationships with healthcare providers create a formidable moat. Demand for immunoglobulins and other plasma-derived therapies is structurally driven by chronic disease and an ageing population.
If the business simply stabilises and resumes steady margin improvement, I believe the current valuation better reflects the risks than it did before. For patient investors, this looks more like a reset than a broken story.
APA Group (ASX: APA)
If I want genuine defensiveness in an ASX portfolio, infrastructure is hard to ignore. That is where APA fits in.
APA owns and operates critical energy infrastructure, including gas pipelines and related assets. These are long-lived assets underpinned by contracted revenues. Demand for energy transmission does not disappear in a slowdown.
What I like about APA is the visibility of its cash flows. Many of its contracts are long term, and the regulated nature of parts of the business provides a degree of earnings stability.
On top of that, APA has historically offered an attractive dividend yield. For a defensive portfolio, a reliable income stream can help smooth total returns during volatile periods.
It's not the fastest-growing business on the ASX, but that's not the point here. In a defensive allocation, stability and cash generation matter more than rapid expansion.
Woolworths Group Ltd (ASX: WOW)
Woolworths is another classic defensive cornerstone.
People need groceries regardless of consumer confidence. Supermarket spending may shift between premium and private-label products, but it does not disappear.
While Woolworths has had operational challenges and competitive pressure to navigate, it remains one of Australia's dominant supermarket operators. Scale, supply chain capability, and brand recognition provide advantages that are not easily eroded.
For me, Woolworths represents a steady compounder. It may not deliver explosive growth, but over time, consistent earnings, dividends, and reinvestment can add up.
Foolish takeaway
If I were building a defensive ASX portfolio today, I would start with businesses that provide essential services, generate resilient cash flows, and have proven staying power.
CSL offers global healthcare exposure at a more reasonable valuation after its de-rating. APA brings infrastructure-backed income and visibility. Woolworths adds everyday consumer stability.
Together, I believe they form a solid foundation for investors who want to play defence without giving up long-term potential.
