Building a passive income portfolio isn't about chasing the highest dividend yield.
If anything, that's one of the easiest ways to get into trouble.
What I'd focus on instead is building something that can grow, adapt, and keep paying me for decades. The goal is reliability first, income second, and growth quietly working in the background.
Here's how I'd approach it.

Start with a foundation of quality
The core of any income portfolio, in my view, has to be high-quality businesses.
These are companies with strong balance sheets, consistent earnings, and the ability to grow dividends over time. They might not always offer the highest yield today, but they tend to be far more dependable.
For me, that includes names like Commonwealth Bank of Australia (ASX: CBA), Woolworths Group Ltd (ASX: WOW), and Wesfarmers Ltd (ASX: WES).
They operate in essential parts of the economy, have pricing power, and long track records of paying dividends.
What I like about this group is that they provide a base level of income that I can feel relatively confident about, even when markets are volatile.
Add infrastructure for stability
If I wanted to make the portfolio more resilient, I'd layer in infrastructure-style businesses.
These are companies that own critical assets and often generate predictable, inflation-linked cash flows.
Transurban Group (ASX: TCL) is a good example, with toll roads that benefit from long-term concessions and population growth. Telstra Group Ltd (ASX: TLS) also fits here, with recurring revenue from its telecommunications network.
These types of businesses can help smooth out income, particularly during periods when more cyclical companies might struggle.
Include income with growth potential
A mistake I think many investors make is focusing only on today's yield.
I'd want a portion of the portfolio in companies that might offer slightly lower yields now, but have the potential to grow their dividends over time.
That could include businesses like REA Group Ltd (ASX: REA) or even TechnologyOne Ltd (ASX: TNE), where earnings growth has historically supported rising payouts.
Over time, these can become some of the biggest contributors to income, even if they don't look like traditional income stocks at first glance.
Use ETFs to tie it all together
Even with a strong selection of shares, I'd still want diversification.
That's where exchange-traded funds (ETFs) come in.
A fund like Vanguard Australian Shares High Yield ETF (ASX: VHY) can provide exposure to a broad basket of dividend-paying companies, helping to reduce reliance on any single stock.
I also like the idea of including something like Vanguard Diversified High Growth Index ETF (ASX: VDHG). While it's not purely income-focused, it brings global diversification and long-term growth, which can support future income.
For me, ETFs are less about maximising yield and more about strengthening the overall portfolio.
Keep some exposure to resources
I think miners have a place in an income portfolio.
Companies like BHP Group Ltd (ASX: BHP) can generate significant cash flow during strong commodity cycles and return a large portion of that to shareholders.
The trade-off is that dividends can be volatile.
That's why I'd treat this part of the portfolio as a bonus rather than something to rely on for consistent income.
Foolish takeaway
If I were building a passive income portfolio on the ASX, I wouldn't chase the highest dividend yield or try to find shortcuts.
I'd focus on quality businesses, add stability through infrastructure, include some growth, and use ETFs to diversify.
By doing so, I think it would put you in a strong position to build a resilient, long-term income portfolio.
