For me, a true blue chip is not just a large company. It is a business with staying power. It has survived cycles, adapted to change, and continued delivering for shareholders over decades.
With that in mind, here are three blue chip ASX shares I would be comfortable buying in March.

Wesfarmers Ltd (ASX: WES)
Wesfarmers is the kind of company I would happily tuck away and forget about for years.
Through Bunnings, Kmart, and its other divisions, Wesfarmers is deeply embedded in the Australian consumer landscape. It sells everyday goods, renovation materials, and essentials that households continue to buy regardless of economic headlines.
What sets it apart is capital discipline. Management will divest underperforming assets and reinvest in higher-return opportunities when the time is right.
Its shares are not always cheap, and it does not always shoot the lights out. But it has a long history of compounding value over time.
That consistency is what I want from a blue chip ASX share.
Commonwealth Bank of Australia (ASX: CBA)
CBA remains the dominant force in Australian banking.
It has scale, a strong deposit base, and a reputation for operational execution. While bank earnings are tied to the economic cycle, CBA has historically delivered strong returns on equity and reliable fully franked dividends.
Critics often argue that it trades at a premium. That may be true.
But premiums are often attached to quality. For investors seeking stability and income, I think CBA continues to earn its place in blue chip portfolios.
BHP Group Ltd (ASX: BHP)
BHP adds global reach and exposure to essential commodities.
Iron ore may dominate headlines, but BHP's portfolio also includes copper and other resources that underpin infrastructure, electrification, and industrial growth.
Commodity prices will always fluctuate. But BHP's scale, balance sheet strength, and asset quality give it resilience across cycles.
It is not a defensive stock in the traditional sense, but it is a cornerstone of the Australian market and has delivered substantial returns over long periods.
Why blue chips still matter
It can be tempting to focus solely on high-growth names.
But blue chips serve a purpose. They anchor portfolios. They generate income. They provide a foundation that allows investors to take selective risks elsewhere.
Not every blue chip will outperform every year. But I don't think that's the point. The point is durability.
Foolish takeaway
Wesfarmers, Commonwealth Bank, and BHP represent three different parts of the Australian economy: retail, banking, and resources.
They are not flashy. They are not new. But they are established, resilient, and deeply embedded in the market.
For investors looking to build a portfolio that can endure, these are three blue chips I would be comfortable buying today.
